Can the MOU with the property buyer be extended after expiry without my approval?

Hello,

I have signed an MOU without any deposit and the MOU expired today. The broker and buyer did not turn up to close the deal and the MOU expired today.

I spoke to another broker but he said that while raising Form A, it's showing Contract F exists.

Earlier it was showing to him Active Contract F exists but now after the expiry of the MOU, it is showing that Contract F exists.

How can this expired MOU be still effective?
