Custom configurations are not available after migration

[knoxi]

After migration, our custom configurations are no longer available in the project properties.
The configurations are still in the project files.
After adding the line <Configurations>Debug;Release;Release_CI</Configurations> in the first PropertyGroup in the project file, we got our custom configuration back.

Can you share an example?

I think what you mean is that you have this?

  <PropertyGroup>
    <Configuration>Debug;OtherConfiguration</Configuration>
  </PropertyGroup>

Is that correct?

[knoxi]

Exactly.

All configurations remains in the project in the PropertyGroups but are not shown after upgrade.
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' "> ...

Before migration:

After migration:

After inserting manually the config they reappear:
<PropertyGroup> <Configuration**s**>Debug;Release;Release_CI</Configuration**s**> </PropertyGroup>
