Can’t Sell Players Bought with Coins – Market Sell Button Disabled

Hello EA Team,
I’ve encountered a serious issue in FIFA Mobile.
Players that I bought using my own coins (for example: Florian Wirtz) cannot be sold anymore. The “Sell” button in the Market is completely disabled for all of them.

I’ve already contacted EA Help, but I haven’t received a response yet.
It seems to be a technical bug that might affect multiple players.
Please check and fix this issue as soon as possible.
