Had the same issue with the same challenges. Restarting the game fixed it for the first match after restarting, then broke the following game. A reinstall fixed it for a long while, but it just started happening again with the WP launcher and revives as support. Reinstalling again to see if it will fix and for how long, but not sure if it will. All challenges I've had this bug with had progression already in the challenge, meaning they have already been unlocked. Not sure if related, but I only started having this issue after I customized my graphics settings as opposed to Auto detection (I downgraded said graphics so less memory is used).
