Prestige Weapon Load Out Reset Bug

[Techbum]

I just went to Prestige 6, and my weapon load outs didn't fully reset. I can select my unlocked items, though I can't use anything besides XM4 in multiplayer. I can select my other unlocked weapons to build a load out; it just reverts to XM4 in the game. No problems with Zombies. I think it has something to do with a wildcard that is locked and that I can't change. Any ideas?

It might be due to the perk which adds three augment slots to your weapons, if it's not unlocked and in use any gun relying on it won't be usable either.
