[COD]Superi 46 weapon XP not tracking — stuck at level 1 after Armory unlock

Unlocked the Superi 46 through Armory and it shows Weapon Challenge Completed, so it’s fully unlocked and usable.

Problem is: it won’t level up at all.

Played 3+ full matches using only the Superi 46 (kills + contracts) and it’s still stuck at Level 1 (1/22) with zero XP progress.

Tried re-equipping, different loadouts, restarting matches — still nothing.

Anyone else seeing this XP tracking bug? Any fix/workaround?
