CHALLENGE TRACKING - Red Bull - Bonus Challenge for Candid Skin

I've won at least 5 matches of Conquest and Team Deathmatch since unlocking the Bonus Challenges for the Red Bull log but it's showing that I've only won 2 matches.

I just checked this after completing yet another Conquest match on Operation Firestorm where our team won by a landslide and yet the challenge has not registered my success.

It'd be great to hear the status of Challenge tracking as I've seen this bug more often with seasonal and weekly events than I have with the usual Daily / Weekly challenge lists.
