Marking Invoices with a Negative Net as Paid

SOLVED

We have a sitution where the total we owe a Vendor is a negative amount.(The net of some positive invoices and a large credit invoice)  The vendor issues us a credit check for the total.  But I cannot apply that check to those invoices. 

So now the invoices still show up on my 'Invoices to Pay list" and my Accounts Payable GL total isn't accurate becuase it should not include that negative balance.

Is there a way to somehow mark those invoices that net a negative as paid?  I tried issuing a $0 check but it only does it for a net of $0, not a negative net amount.
