Unable to change players in Radomiak Radom team (Polish Ekstraklasa League)

When selecting Radomiak Radom in EA FC 26, it’s impossible to change any players in the lineup.
The issue occurs both before the match and during the game (from the pause/settings menu).

The only way to substitute a player is through Quick Sub suggestions during a match.

Steps to reproduce:

Enter any game mode (for example, Kick-Off).
Select Radomiak Radom as your team.
Try to edit the lineup – no player changes are possible.
Start the match and attempt to make substitutions from the pause menu – still not possible.

Expected behavior:
Players should be able to edit the lineup (change players) both before and during a match, just like with any other team.

Platform: PC (EA App)
Game version: EA FC 26
