After updating from Student Billing 7.78 to 7.80, records that have a balance of $0 are included on the Aged Accounts Receivable Report even if you filter the report on a query of records that have a balance that does not equal 0. The Aged Accounts Receivable Report is showing records with zero balances and showing paid transactions as line items with zero amounts.
We resolved this issue in version 7.82.104, patch 4.
