After paying supplier's invoice, it still shows on Aged Payables Report

I’m using Sage 50 US.  When I pay a supplier’s invoice before the due date, the invoice still shows up on the Aging report, but now as a negative dollar amount.  The report subtracts that from the total amount due for that column, which makes the total amount due on the report (and on the “Business Status” home screen) incorrect.  I’ve looked at the possible filters on the report to see if “select if unpaid” or something similar was available.  I’ve been exporting to Excel and manually removing the paid invoices.  Does anyone have a solution that would exclude the paid invoices from the report within Sage?  Thanks in advance!
