Hero stuck on quest

My Chomzilla is also stuck on a quest won't go past quest number 9 (win a game with 20 health) even though I have won the games a few times with 20hp on my character but nothing won't let me proceed to quest 10 ☹️ 

For me it's quest 6 for Grass Knuckles.  Won several games by tbe end of turn 6, latest by end of turn 4, but will not progress.  

I have the same problem with quest 6 for Grass Knuckles.

Won games by the end of turn 5 and 6 several times, even won two times when opponent surrender on turn 1,2 and 3.
