Locked items after completing assignments (based on revised requirements)

This issue has been present since the requirements were updated for assignments.

“Unlocked” items including weapons, gadgets and skins are still locked in loadouts because the game hasn’t registered the completion of each assignment — even though the player was notified. 

No workaround has fixed the bug, despite recommendations from EA Help.
