I received a payment from a customer and tried to enter it, but I get a notice that says, "I know this customer has open invoices.  Why don't they show up in the invoice table?" and gives 2 suggestions how to resolve it.

Neither work.

The situation is a single customer shows a positive balance when I look at the balance in the Customer Center and when I run a "Customer Balance Summary" report of $66.03.  But when I run an "A/R Aging Summary" report, it shows a negative balance of -$120.17.

Does anyone know what could be causing this?  I've attached 2 screenshots to illustrate.

TIA.
