Completionist Camos not working

[noobz0]

I've recently done the 4 camo challenges for the Kastov 762, which, I think, should unlock the next step, that being, the gold camo challenge for this specific weapon, but that hasn't happened. The little bar the sits above it (golden camo) was almost full, when I completed the last challenge, it reset to zero (like the other completionist camos are); Also on the "Weapon Mastery" tab, for some reason, it says I have "Polyatomic" camo unlocked, which, well, I don't.
Anybody else having a similar issue?
