Finishing weekly challenges but not getting to claim

I finish the weekly, monthly, and special challenges but when I go to claim it, it won't let me. Either show blank spots or over counts. Like the 250 pt sequences. I have to do 20 but my counter is showing over 200. It won't let me claim it and this has happened so many times. I've lost who knows how many points and tiks because of this. It does this a lot with my party challenges too. Won't give me credit for them. On top of that my game has been freezing a lot doing party challenges. I've been playing since day one and it bothers me a lot to think of what I haven't earned because of these issues. I do love the game though. It's my go to game rn for sure.
