UNET SyncVar on server side not updated

Question

I am trying to use SyncVar but I do not fully understand what I am doing wrong, if I do it wrong that is. Here is the situation:

1. I have two public SyncVar's: redFunds and blueFunds and two local "old"-version to compare with

2. I initiate the SyncVar in Start by using Cmd_UpdateXxx, that works

3. I have two buttons, one for each SyncVar

4. In Update I compare the SyncVar vs. the oldXxxFunds. If a hit I display on scene

When I run the code it does display the correct numbers on the scen on both players (Red & Blue) but that is not fully reflected in the editor when looking at the "public" SyncVar's. When pressing the red button it only reflect, in the editor, on the red player not the Blue.

Can someone explain to me what i am doing wrong here? ...if I am doing something wrong that is. Shouldn't I see the changes in the editor as well?

[SyncVar] public int redFunds;
[SyncVar] public int blueFunds;
public int oldRedFunds;
public int oldBlueFunds;

private void Start () 
{

    if (!isLocalPlayer)
        return;

    Cmd_UpdateRed (10);
    Cmd_UpdateBlue (20);
}

// Button
void btn_Red () 
{
    if (!hasAuthority)
        return;

    Cmd_UpdateRed (10000);
}

void btn_Blue () 
{
    if (!hasAuthority)
        return;

    Cmd_UpdateBlue (20000);
}

[Command]
void Cmd_UpdateRed (int _value) 
{
    redFunds = _value;
}

[Command]
void Cmd_UpdateBlue (int _value) 
{
    blueFunds = _value;
}

void Update () 
{
    if (redFunds != oldRedFunds) 
    {
        txt_RedTotalFunds = GameObject.Find ("txt_RedTotalFunds").GetComponent<Text> ();
        txt_RedTotalFunds.text = "$" + redFunds;
        oldRedFunds = redFunds;
    }

    if (blueFunds != oldBlueFunds) 
    {
        txt_BlueTotalFunds = GameObject.Find ("txt_BlueTotalFunds").GetComponent<Text> ();
        txt_BlueTotalFunds.text = "$" + blueFunds;
        oldBlueFunds = blueFunds;
    }
}

The best way I can think is to use a GameRoomInfo as an network object owned by the server.

It can be done with 2 simple scripts as follows:

GameRoomInfo Script

using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.UI;
using System.Collections;

public class GameRoomInfo : NetworkBehaviour
{
    public Text txt_RedTotalFunds;
    public Text txt_BlueTotalFunds;

    public int oldRedFunds = 0;
    public int oldBlueFunds = 0;

    [SyncVar]
    public int redFunds;
    [SyncVar]
    public int blueFunds;

    void Update()
    {
        if (redFunds != oldRedFunds)
        {
            //txt_RedTotalFunds = GameObject.Find("txt_RedTotalFunds").GetComponent<Text>();
            txt_RedTotalFunds.text = "$" + redFunds;
            Debug.Log("Red - $" + redFunds);
            oldRedFunds = redFunds;
        }

        if (blueFunds != oldBlueFunds)
        {
            //txt_BlueTotalFunds = GameObject.Find("txt_BlueTotalFunds").GetComponent<Text>();
            txt_BlueTotalFunds.text = "$" + blueFunds;
            Debug.Log("Blue - $" + blueFunds);
            oldBlueFunds = blueFunds;
        }
    }
}

Player Script

using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.UI;
using System.Collections;

public class Player : NetworkBehaviour 
{
    public enum PlayerColor
    { 
        Red, 
        Blue
    };

    //used to update the right variables (Blue player updates blueFunds and Red player updates redFunds)
    [SyncVar]
    PlayerColor playerColor;

    static int colorSelect = 0;

    void Start()
    {
        if(isServer) 
        {
            // the server selects the player color when created
            switch(colorSelect % 2)
            {
                case 0:
                    playerColor = PlayerColor.Red;
                    break;
                case 1:
                    playerColor = PlayerColor.Blue;
                    break;
            }

            colorSelect++;
        }
    }

    void Update()
    {
        if (!isLocalPlayer)
            return;

        if (hasAuthority && Input.GetKeyDown(KeyCode.KeypadPlus))
        {
            Cmd_UpdateAdd(10);
        }
    }

    // Button
    void btn_Update()
    {
        if (!hasAuthority)
            return;

        Cmd_Update(0);
    }

    void btn_Add()
    {
        if (!hasAuthority)
            return;

        Cmd_Update(10);
    }


    [Command]
    public void Cmd_Update(int _value)//The command updates the GameRoomInfo variables according to the player color
    {
        switch (playerColor)
        {
            case PlayerColor.Red:
                FindObjectOfType<GameRoomInfo>().redFunds = _value;
                break;

            case PlayerColor.Blue:
                FindObjectOfType<GameRoomInfo>().blueFunds = _value;
                break;

            default:
                break;
        }
    }

    [Command]
    public void Cmd_UpdateAdd(int _value)
    {
        switch (playerColor)
        {
            case PlayerColor.Red:
                FindObjectOfType<GameRoomInfo>().redFunds += _value;
                break;

            case PlayerColor.Blue:
                FindObjectOfType<GameRoomInfo>().blueFunds += _value;
                break;

            default:
                break;
        }
    }
}

I have made some small changes to help testing. Feel free to adapt to your needs.
