Challenge progression rollback

Hello,

I was playing and trying to grind the challenges for the skins and stuff.

I had finished most of them, then all of a sudden while playing. Alot of the challenges rolled back setting me back and losing a couple of the rewards, so it seems.

Is guess this would happen with actual release challenges.

Edith: checked again, progression lines look full. The numerical counter says something else. Added a picture.
