Rapid Fire & Danger Close Still Bugged

It's been a week since the challenge/weapon requirements were reduced. At that time, I was actively working on the Rapid Fire and Danger Close challenges to unlock the weapons involved. Last Friday comes, and the challenge requirements were reduced. Both challenges show complete, yet I'm unable to use either weapon. This is extremely frustrating, as I would have had them unlocked at this point pre-nerf.

I have restarted my computer and steam, I have played for hours on multiple game types. Nothing seems to actually unlock these weapons. Please advise.
