DLC not showing proper interaction prompts

[User76]

So I have a steam copy of black ops 2, also mob of the dead and nuketown, I wanted to play origins, but instead of interaction prompts saying "Press F to interact" they instead say things like "ZM_TOMB_CH_V"
Here's a screenshot:

apparently the localization files in t6_full_game makes these prompts not bugged.

What language is your game on steam?

English, again apparently the localization txt files included in t6_full_game make these prompts not bugged.
