Screenshot showing the menu entries in GNOME
Description of problem:
Some menu entries are unlocalized like `pt_BR` (is `pt-BR` in the file, which is not compliant with spec - https://specifications.freedesktop.org/desktop-entry-spec/latest/ar01s05.html).
Version-Release number of selected component (if applicable):
Open the menu in the GNOME dash or in the top bar.
Show menu entries in English.
Show menu entries in user locale.
Do I understand correctly that we need to change pt-BR to pt_BR (and others) in the desktop file? If so can you test if that actually works?
