Squad Edit Bug: New NT Players Disappear / Historical XI Duplicate [PS5]

Following the latest squad update, two severe and interconnected bugs have been detected in the customization menu when transferring players to any club or Free Agents:

1. New National Teams Added in the Update (e.g., Alaba with Austria): When transferring a player to a new club, the player joins the destination team correctly but completely disappears from their national team. When attempting to replace them in the "Edit National Teams" menu, the squad database gets corrupted, and the game only allows a maximum of 25 players to be called up instead of the regulation 26, permanently locking one slot. This does NOT happen with national teams that were already in the game prior to the update.

2. Historical XI Teams (e.g., Real Madrid Historical with Carvajal): When transferring a player from these specific teams to any other club, the player is not moved properly; instead, they duplicate. They will appear in their new destination club while simultaneously remaining intact in their original Historical XI team.

This disappearance or duplication issue does not affect players who were already assigned to Free Agents by default before making the changes.

System and Game Details:

- Platform: PlayStation 5 (PS5)

- Game Mode: Customize / Edit Teams / Club Transfers & National Squads

- Date of the issue: June 2026

Steps to Reproduce the Bug:

Case 1 (New National Teams):

1. Go to Customize > Edit Teams > Club Transfers.

2. Select a player from one of the new national teams added in the latest update (e.g., David Alaba from Austria).

3. Transfer them to any club or Free Agents.

4. The player will show up in the destination team, but when checking Edit National Teams, they will have disappeared from Austria, and the maximum squad call-up limit will glitch, being capped at 25 players.

Case 2 (Historical XIs):

1. In the Club Transfers menu, look for a player who is part of a club's Historical XI (e.g., Dani Carvajal).

2. Transfer them to any other club in the game.

3. Check both squads: the player will have duplicated, being present in both the new club and the original Historical XI team.

What troubleshooting steps have you tried?

I have tried resetting the squads to default and redownloading the latest online squad update, but both errors consistently and systematically recur.
