Bl3 coop nametag disappearing

Whenever I play multiplayer BL3 Steam with my other 3 Steam friends, the nametags above their heads randomly disappears making it very difficult to track them especially in a battle or when someone has been downed. It fixes itself when we enter/exit a zone but then randomly disappears again which isnt even a fix at this point. Is there any fix for this and is Gearbox even aware of this issue as it seems to be a recurring one.
