zombie dlcs no voicelines

[minilutin12]

hello, i've been doing easter eggs on zombie with my friends, and when we did die riese, i noticed there was no voice line at all, when we needed the voice line to know if we did the step or not. i verified my game files, steam and plutonium, i reinstalled the game, checked my settings etc but still no voice lines, anyone have any clue of what i can do ? thank you
