Level problem in league

[July Fourth]

Hello
I have a problem
I am Level 19, all the other teams in my league are Level 20.
Please to be fine.
Thank you!

This can happen on 2 ways, first way is there is an odd one out situation and the game has to put a level 19 club in a level 20 league to ensure they are 14 clubs in the league. The other way is that you have level 20 friends and the game has thrown you in that league so you can play against friends.
