[PC] Weapon loadouts reset when joining a match and in-menu plus system glitch

When I create weapon loadouts in the menu they are saved at first (as in I can browse the menus, return and they'll still be there) but whenever I join a match, all weapon loadouts reset...

So all the equipped attachments on the plus menu disappear in-game (except for the standard ones).

If I try to add the attachments back in the in-game customization screen, the selected attachment gets added on the icon with the plus still in it (so two icons at the same time) and it removes the attachment when pressing the back button... 

This is a pretty frustrating issue because I want to utilize the plus system to the max with all of the cool attachments I've unlocked. 

Does anyone have the same issue?

Is this already known at EA/DICE?

Is there a fix for this?

Please let me know!
