Tradeable Players on FUT becoming untradeable

I have had several players on FUT becoming untradeable despite them being tradeable. I have requested help from EA chat but they can't see anything on their end. I have Nico Williams worth 200k and was looking to sell and 2 days later its locked as untradeable. I have had other people I know also have the same issue. Please can anyone with the same issue comment and lets get this resolved. Hopefully EA FUT developers can sort this bug out.

Thanks
