USG-90 showing weird Text in modify Window

Sup, found this while checking out some weapons. I don’t know if it’s only in the German version of the game, but yeah — magazine attachment showing 'ID_ARRIVAL_RANK_36'. I don’t think it’s supposed to say that.

Note: I’m level 22 and haven’t unlocked the weapon or the attachments for it yet, just in case that’s important.
