Error during AP check voiding

Has anyone else had this problem before?

Thanks, Cindy
We are running Vantage 8.03.408B, and I have come across an error that I haven't seen before, so I am hoping that one of you can help me.  Recently we made a partial payment on an invoice, and posted the payment.  We then voided the payment, as usual.  Everything seems to look okay, but we are not able to pay the entire invoice now. 

In the AP Aging Report, the entire balance shows on the report, correctly.  In the AP Invoice Tracker, under the Header tab and Payments tab, if shows the payment, and the voided payment, correctly.  In the Supplier Tracker\Invoices\Open, it shows the entire amount correctly in both the "Amount" and "Balance" columns.  However, when we try to set up a new payment to pay, it will only let us pay the balance after the original payment had been made.  In this screen, it's as if the payment was never voided.

Has anyone else seen this problem before, and if so, how do you correct it?  I wasn't sure if there was a Conversion Program that might correct this error.

Thanks, Cindy
