A tradable player incorrectly became untradeable

I have written about this many times. Two of my complaints were deleted by the system! My player Bernardo Silva was tradable, but suddenly became untradeable for no valid reason. I also tried while the player was not in my active squad, but it still did not work. He is not registered to any squad or lineup either. No matter what I do, I cannot sell him.

Please finally fix this issue.
