I think I understand what the topic starter is trying to tell us. Since I use Ubuntu Budgie 20.04 with the Cupertino desktop layout, I also automatically use the Global Menu. Therefore I can understand the problem described. If you click on “Desktop” in the Global Menu, you are presented with two options: “Desktop Settings” and “System Settings”. One would expect that the two options presented to the user here also lead to two different settings menus, namely the “Budgie Desktop Settings” and the “Settings”. Both options, however, lead to the “System Settings” menu, which the topic starter calls the “system menu of GNOME”. This and the fact that the Global Menu for the Desktop, i.e. when no application is active, always remains in English, regardless of which system language is set, can be confusing for the user.
