My Gig on Hold - need to reinstate it


I was doing OK with my GIG but for some reason on one of my sales it is coming up under To Do as “Buyer requested a modification - please redeliver” or similar. Problem is the gig HAS been modified and delivered and customer is happy. I am guessing that is why my gig has been placed on hold and don’t know how to get the gig reactivated. Can anyone help please
