Mongo shell and result from code returns different results

I'm new to mongodb and go and was trying to follow an example, but can't check for data in mongo shell since they return different results

my go code


    package main

    import (
        "context"
        "fmt"
        "log"

        "go.mongodb.org/mongo-driver/bson"
        "go.mongodb.org/mongo-driver/mongo"
        "go.mongodb.org/mongo-driver/mongo/options"
    )

    //Trainer You will be using this Trainer type later in the program
    type Trainer struct {
        Name string
        Age  int
        City string
    }

    func main() {
        // Set client options
        clientOptions := options.Client().ApplyURI("mongodb://localhost:27017")

        // Connect to MongoDB
        client, err := mongo.Connect(context.TODO(), clientOptions)

        if err != nil {
            log.Fatal(err)
        }

        // Check the connection
        err = client.Ping(context.TODO(), nil)

        if err != nil {
            log.Fatal(err)
        }

        fmt.Println("Connected to MongoDB!")

        collection := client.Database("db_test").Collection("trainers")

        ash := Trainer{"Ash", 10, "Pallet Town"}
        misty := Trainer{"Misty", 10, "Cerulean City"}
        brock := Trainer{"Brock", 15, "Pewter City"}

        trainers := []interface{}{ash, misty, brock}

        insertResult, err := collection.InsertMany(context.TODO(), trainers)
        if err != nil {
            log.Fatal(err)
        }

        fmt.Println("Inserted a single document: ", insertResult.InsertedIDs)

        result, err := collection.Find(context.TODO(), bson.D{}, options.Find())

        if err != nil {
            log.Fatal(err)
        }
        fmt.Println("Find Failed.")

        for result.Next(context.TODO()) {
            var singleRow Trainer
            err := result.Decode(&singleRow)
            if err != nil {
                log.Fatal(err)
            }

            fmt.Println(singleRow.Name, "+", singleRow.Age)
        }

        fmt.Println("Find finished")

        err = client.Disconnect(context.TODO())

        if err != nil {
            log.Fatal(err)
        }
        fmt.Println("Connection to MongoDB closed.")

    }

this returns 


    Connected to MongoDB!
    Inserted a single document:  [ObjectID("5da929e60a2ef8952d92ce8c") ObjectID("5da929e60a2ef8952d92ce8d") ObjectID("5da929e60a2ef8952d92ce8e")]
    Find Failed.
    Ash + 10
    Misty + 10
    Brock + 15
    Find finished
    Connection to MongoDB closed.

Is it because the mongo shell and my go code connect to different clusters or something? Also I've tried using compass and it shows a different result than the mongo shell too. How do i know the shell is working properly?
My path environment was set to "C:\Program Files\MongoDB\Server\4.2\bin" so i dont think there's a problem with that

Try running your Go code, after replacing the following line

clientOptions := options.Client().ApplyURI("mongodb://localhost:27017")

with this 

clientOptions := options.Client().ApplyURI("mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb")
