Ultimate Gauntlet 12 issue

I’ve now played multiple gauntlet 12 matches and they aren’t logging my progress when I win or an opponent disconnects. No problem in game, it’s when the match is over. I get kicked out of ultimate team altogether and it doesn’t register the game as played, never mind the win. It’s impossible to complete making the advertised rewards impossible to obtain. Please either fix it or award the packs. Xbox, cross play off.
