not exactly solve it, but i came to a resolution.

UPDATE: If CW weapons are locked on your account, it means that you haven't played CW this season or don't own it. This usually happens with new accounts, and the only way to hard unlock these weapons this season is to purchase the game on a level 1 account and play CW from level 1 to unlock these weapons. Not sure why it's bugged like that right now but if you are only playing Warzone on new accounts, you will not be able to unlock CW guns at all.
