Unidentified payment on Aging 7 buckets report

Using AR Aging 7 buckets report by Account, I had run for one customer.

This customer's receipt initially received as Unidentified Receipt and later it has been accounted as On Account Receipt. CCID are different for Unidentified Receipt and On Account Receipt.

When we ran the report, it returns two lines with one line as '0' balance for Unidentified Receipt, while On Account Receipt shows the customer's payment.

It is highly confusing when the Unidentified Receipt shows as a line with '0' balance.

When checking the accounting of this receipt there are

Remitted Cash lines (2) with '0' balance
