Hello, Welcome to Micorosoft Q&A,
In general, we often set Language as x-generate like the following in the package manifest file.
<Resource Language="x-generate"/>
Each time Visual Studio produces your built app package manifest file (AppxManifest.xml), it expands that single Resource element in the source file into a union of all the language qualifiers that it finds in your project.
If you used expanded list of <Resource> elements in your app package manifest source file (Package.appxmanifest) (being careful to list the default language first). That option involves more maintenance work for you. Please try to use <Resource Language="x-generate"/>
to replace your mentioned above.
