OWN THE LOT Tasks not registering correctly

So I was at 30/35 for my "Complete Goals in Own the Lot Challenges". Got a group to do challenges and only got 4 of the 5 goals, the task didnt register so I thought maybe I needed to get them all done for it to go through, but nope. Once I finally got all 5 goals completed, the game freezes on the recap screen and when I close the game and reopen it, only got 1 of the 5 goals marked for the task making it 31/35. Thankfully I got a recording of this happening. It just kind of a bummer to miss out on a limited cosmetic even though I did what was asked of me... I even closed the game and reopened it but still wasnt there. Please help? Thank you
