Re-issued check as recommended here: created a deposit for the same amount, then re-issued the check. Cancelled each other out at next bank reconciliation.

That said, how do I get the AR account (original check was a refund to the customer) to show properly? Right now, when I run an AR report, I get a an open debit and an open credit (end result is zero). How do I apply one to the other to get it off the AR report?
