Players switch positions at kickoff despite correct custom tactics

I want to report a major bug in FC27 Ultimate Team.

Issue: My players keep changing position when the match starts instead of staying in the position I assigned them. This happens consistently even when they have proper chemistry and role cards.

Example: I put James as LM but he automatically moves to a different position when the game starts.

This is frustrating and ruins squad building strategy. Please investigate and fix this bug.
