Challenges not unlocking items

On PC (via EA play) and have had an issue the last few days where the assault team challenge shows completed and that the quark deployment beacon is awarded.

It isn't! It can't be added to the loadout. Have reset cache and repaired. Also the same on a second PC. Completed many different matches. Tracked  / untracked challenges, tried activating XP boosts, also repeating some of the challenges.

Still shows locked in loadout but unlocked in the challenge. Of course can't even progress on the assault challenges as the next one needs the beacon.

I think this is related to the challenge targets being changed a few days ago.
