I've checked and see you have an active contract with your freelancer. You can create and fund another Milestone by going to My Jobs > and clicking the green Activate next Milestone button.

It will be your JOB POSTING that has expired.
NOT the contract
Those are two completely different things.
It is good practice to close job postings when you hire a freelancer (provided you only want to hire one) so others don't waste their connects applying to it.
