Some translated strings not showing up

[Ph_We]

Hi @astevens, @witold,

I can confirm the issue still exists in OJS 3.1.0-1. But it seems to be related to the Main Menu only:

[OJS 3.0.2 --> 3.1] Main Menu is Corrupted

Now we have upgraded from 3.0.2 to 3.1.0-1 and the issue with the English and Russian locales seems to be fixed. But now every other locale has the same issue. We tried French (Canada), French (France) and German. All of them do not have any translation keys for the main menu.
