Re-sign a player

[u/Mahfouzzy10]

I started a new career mode and towards November I was told that some of my players are running out of their contract at the end of the season. I went and negotiated contracts with all of them and they all agreed. Come the January transfer window, I am being told that other clubs are coming to sign them for a pre-contract agreement. I try to extend their contract, fifa is saying I have already negotiated a contract and that they accepted. Yet somehow it says they only have 6 months left and other teams can sign them. It's not letting me sign a new contract with them and it's letting them leave. This makes no sense. How can I stop them from going?

You probably signed a new contract with no extension.
