.Net Core project does not find the SDK or so it seems

I am using instructions from https://learn.microsoft.com/en-us/azure/azure-functions/functions-create-first-function-vs-code to try and build my first Azure Functions project in .Net Core

My problem is I cannot build it:

PS C:\work\proj> dotnet build .\proj.csproj
Microsoft (R) Build Engine version 16.1.76+g14b0a930a7 for .NET Core
Copyright (C) Microsoft Corporation. All rights reserved.

c:\Program Files\dotnet\sdk\2.1.4\Sdks\Microsoft.NET.Sdk\build\Microsoft.NET.TargetFrameworkInference.targets(135,5): error : The current .NET SDK does not support targeting .NET Core 2.1.  Either target .NET Core 2.0 or lower, or use a version of the .NET SDK that supports .NET Core 2.1. [C:\work\proj\proj.csproj]

Build FAILED.

PS C:\work\proj>

Here is the project file:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="1.0.28" />
  </ItemGroup>

      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

I have installed the latest .Net Core SDK from https://dotnet.microsoft.com/download/thank-you/dotnet-sdk-2.1.700-windows-x64-installer, so:

PS C:\> dir 'C:\Program Files\dotnet\sdk\'


    Directory: C:\Program Files\dotnet\sdk

PS C:\>

I do not understand why the build selects version 2.1.4. What am I doing wrong?

EDIT 1

I am pretty sure it is related. For some reason I have environment variable MSBuildSdksPath:

PS C:\> $env:MSBuildSdksPath
c:\Program Files\dotnet\sdk\2.1.4\Sdks
PS C:\>

Installing the latest SDK did not update it. Why?

Build succeeds when I remove it in the local console. Is it safe to remove it from the environment variables at all?

EDIT 2

PS C:\> dotnet --list-sdks
1.0.0-preview2-003131 [C:\Program Files\dotnet\sdk]
2.1.4 [C:\Program Files\dotnet\sdk]
2.1.403 [C:\Program Files\dotnet\sdk]
2.1.500 [C:\Program Files\dotnet\sdk]
2.1.502 [C:\Program Files\dotnet\sdk]
2.1.507 [C:\Program Files\dotnet\sdk]
2.1.700 [C:\Program Files\dotnet\sdk]
PS C:\>

I had this problem after cleaning up previous sdks before 3.0.0. I had installed an x86 version before. I didn't want to installed both X86 and X64 versions again. I looked at my envirnment variables and and saw an entry in the PATH pointing to the dotnet folder. I changed it to be C:\Program Files\dotnet\ and now I'm okay.
