Cash receipt error

Getting this error when trying to apply a cash receipt to an outstanding invoice:

Amount to Allocate cannot be more than Balance Amount

When I look at Invoice Tracker, the invoice is still outstanding with a balance. When I look under the cash receipt entry screen and look under the Invoice Selection tab, there it is, with a $60K balance.

I created a BAQ to see if there are any other unposted cash receipts that reference this invoice, none are showing up. Not sure what else to check.

Balances were wrong for some reason, had to use an Epicor fix to update the balances.
