BUG FC 26 : formation changes not applied in season mode - ps5

Hi, 

Please EA SPORT : fix it 

i play on PS5

mode : season online

when i config a new formation, change is not applied, i can play only with 1 formation, 

even with the only one formation i can play, if i make a little change, for example a player's role, it does not keep the change. 

please fix it, it's essential to play at least with 2 or 3 formations to change during a game. 

feel free to contact me if needed +33769025151
