Trouble with the tournament

Knockdowns go to 9 and go back to 7 every time I win a battle, so I can’t complete the tournament’s 10 takedowns as I had this problem 2 times when I won.

Seen this before. Restart game and it should be updated correctly to 10 wins.

I’ve had this happen before. Restarting the game usually helps, as does rebooting your phone.
