Any1 else have these problems that patches/costume items are not unlocking?

For example:

I've done the challenges that require 2 Kill with 1 sniper bullet ( This unlocks a Patch )
I've done firing an entire snipe mag without missing ( This unlocks a Patch )

But they are still locked ;/ ?

Chellenges are realy buggy lol. I need to do 15p kill with red dot, im at minimum 4000, and it says: 6/27. Lol

Ah seems I know how it works now, some Mod on COD forums is saying that, iff you want to unlock anything, it has to be active at Operations... LOL

Edit:

When @ Operations, u need to activate them. Also u can buy new operations with square ( ps3 ) if u cant find the patch or w/e unlock u want u can rebuy operations for 1 squad point.. XD
