Not sure this should go in Translations and/or if it's a general issue or only in a few languages.
I use Mate in french. In language settings, I have french above all (and english below), have installed the french language packs and have applied the settings system-wide. So, my system should be entirely in french.
Yet, the Control Center displays some entries in english, like "Network", "Printers", "Software and updates" and so on. Some are in french as expected but ~15 stay in english.
I first thought the issue came from the corresponding launchers (in /usr/share/applications), as checking their content I can only see the generic english name and no translations (no Name[fr] line). But I've just noticed that all the launchers are correctly translated in the System menu.
So I don't really understand 1) where the menu gets its translated launchers names from and 2) why the Control Center doesn't get them.
Any idea as to what is happening exactly?
EDIT : I should add that from what I remember, the issue wasn't there in Ubuntu Mate 15.10 (Mate 1.10) but I first noticed it when using the PPA to update to Mate 1.12. I then removed it and all was fine again. Then, it happened again after upgrading to Ubuntu Mate 16.04. Would it be an issue specific to Mate Control Center 1.12?
