Perks Fail to Progress, reset to Zero ( 0 ) or revert to an earlier state

If this appears to happen to you on the PlayStation 4 platform this is a visual only glitch and it should fix itself when you next join a server/game. If this does not appear to clear up you should attempt to Rebuild your PS4 database:

If your perk level has reverted to an earlier state your save file has corrupted and your PlayStation 4 system has chosen a recent uncorrupted save file to use instead.
