CANT FIND UNASSIGNED ITEMS

Hello, I was removing evolution upgrades from my players (Pele and Mbappe) and the system glitched. It showed a message saying 'player has been moved to the unassigned pile', but the cards completely disappeared. They are not in my club, not in unassigned, and not even in Quick Sell Recovery. I was removing the evolutions because the Mbappe was tradeable and wanted to change positions for Pele. What do i do?
