GK RUNNING FROM GOAL, PLAYING FROM THE FIELD AND HAVING MY STRIKER IDLE

Guys i opened EA FC 26 to play some matches of online season, for now in 5th div and when i got matched with someone, from the beggining of the match Lewandowski my striker was idle, not touching the ball and staying in one place. Then I see my Gk Joan Garcia run around in my defense in a shirt of a field player, not his gk one and no one is at my goal. So its really easy to score goals against me and it got me 4 losses in a row thanks to this. I tried to turn it off and on, reinstall the game but nothing helped. Any ideas what to do with this? Thanks
