I can' upload my app to the Microsoft store, because the Package Family Name (PFN) is wrong.

I have a problem, when I create a Windows App from a .Net Maui App (it’s a WinUI3 app) and try to upload it to my store (msix file). I get an error in store that the Package Family Name (PFN) is wrong, even though the Package.appxmanifest seems to have the correct values. The Package Family Name (PFN) is not directly set in the Package.appxmanifest, but Visual Studio shows me, that it has the right value, like in the bug is expected.
How can I fix the issu?

I forgot to add that also the Publisher seems to be wrong. In the Package.appxmanifest the Publisher is like "CN=4D....." but in the error description it just the name of my company "Soft...."
