I think this change happened back in June 2018. There were many discussions on the forum, going back years, about whether aging reports should include deposits or only invoices (for both receivables and payables). An example is this discussion: Accounts Receivable CREDIT Balances not shown in Aged Receivables Listing.
Basically, some prefer an aged receivables report to only include receivable invoices. Others believe the report should match the Accounts receivable balance. Accounting references and texts can be found supporting both viewpoints. The current format does no harm. The report does not go to customers. This is not an error, as your original title suggested. It reflects a formatting decision.
