[BO6] I can't access my loadouts when I join a multiplayer game. Any solutions that really work?

I just got to prestige 2. When I join a MP game every main weapon on my loadouts is a MX4 with no attachments.

I know how prestige works. I have unlocked permanently every weapon I have on the loadouts.

In prestige 1 it worked just fine.

Does anybody know what to do?
