Players duplicate during club transfers (Edit Teams)

In the main menu under Edit Teams → Club Transfers, some players are duplicated and assigned to multiple clubs at the same time. The affected players show “XI” after the club name (e.g. Bayern XI or Liverpool XI). When transferring these players, they are not moved correctly and remain in both clubs, making transfers impossible. This issue occurs outside of any game mode, affects the global squad database, is fully reproducible, and has persisted for several weeks despite updates. An EA Support case exists (case #232032528).
