The ageing on our statements is displaying incorrectly. Invoices entered with a December date are showing in the ageing on the bottom of the statement as being current. What am I doing wrong?

Here's my issue:
I posted payments received to a client ORDER (invoice not created). When I print statement, the payments do not show and the balance says "0". Something is wrong: "GENERALLY ACCEPTED ACCOUNTING PRACTICES" say that the client would have a credit balance! This does not make sense; several years ago, the version did just that, and printed all the payments and a credit balance.

If anyone has comments, PLEASE.

If support reads this, PLEASE, is there a workaround?
