I issued the refund from the Credit Memo and from Prepaid as an Item.  I do go back to the Previous Payment Screen and when I press issue refund check, it will change the entire transaction as it was from four months earlier and the credits have been applied to fees.  I can see the applied credits....do I change the date and the amount to match the overpayment?  That doesn't seem right as it will change my applied credits.  If I try to issue the credit from the payments screen, the available credits show at the bottom, but cannot "refund check".
