MuseScore 4 cannot see/use my custom templates (Ubuntu Linux)

Hi there!

I was hoping someone could help. I have the latest MuseScore 4.0.2 downloaded from the website using the Appimage to Ubuntu Linux.

For some reason, MuseScore cannot or will not see my custom templates in the template folder. I have checked the folder location in Preferences>General>Folders, and have even changed the folder multiple times. I have restarted my PC multiple times too, but to no avail. I still cannot create a score from any custom template in any folder.

Perhaps this is a bug, or perhaps I’m doing something wrong?

Any help would be greatly appreciated.

Thanks in advance.
