[2019] Holger 26 Not tracking last camo!

I’m stuck on the last camo of the holger 26, skulls (get 3 kills without dying). It has been stuck on 23/25 for the last 4 games. I know I have completed the challenge multiple times but it doesn’t budge. That’s not even the worst of it either, if I use the gun at all in a game nothing tracks, no missions, no battle pass xp, no player level xp nothing. Please help/fix this, I just want to play with the new content but if I do I will lag behind on leveling up my battle pass and character!
