I did a quest but the game says i didnt

Same problem, I trained more than 20 players to level 30, but it stopped counting after 7,  it is now stuck at 7/18, even though I trained more than 20 players to level 30.

Hi there — thanks for flagging this issue with the quest. I’ve reported it to the team for review, and I appreciate the feedback. If you completed the objective only recently, please try restarting the game, clearing the cache, and completing another objective to help sync your account. Thanks!
