Challenges not tracking.Fix it

Casually challenges do not track.Even after restarting PC and game.I wasted all of my challenge swaps and now I am stuck and cannot finish the event.Since I am a normal person who has a job I don’t have time to waste it on some stupid challenges.To buy new challenge swaps it’s nothing for me but I don’t want and I won’t buy anything till the games it is Complete,Fixed and Finished.
