can not save the edited squads file, it's been defaulted when restart the game

I have encountered a serious bug in the FC26 game on my PLAYSTATION 5 platform, I cannot save the edited national team & Club squads both in the main menu and World Cup Mode. Once I restart the game, Squards all been reset defaulted. That’s really ruined my mood, It means everytime I start the match I must re-edit the squads. Please fix it ASAP, TKS.
