Can’t Sell Éder Militão and Hincapié Cards on Transfer Market

Hi, I’m experiencing an issue with my Ultimate Team. I recently bought the Éder Militão and Hincapié cards, but now when I try to sell them, the game says it’s not possible to list them on the transfer market. I’ve tried restarting the game and checking if they were untradeable, but they should be tradable. Could you please look into this issue or let me know if it’s a known bug? Please help...
