Vantage 8.03 - Payment Posting Issue

One of our accounting clerks created & posted a manual check. The Payment Register Report shows a "?" for the Payment Amount and when the accounting manager tries to do a bank reconciliation she gets an error. If we look at the check through payment tracker it shows a payment. We were able to get around this by voiding the payment and creating another but we need to know what caused this.

Has anyone else experienced this, if so were you able to determine a cause? Also, were you able to correct the problem without voiding the payment.
