This might happen due to the amount in the parent account. To check this, you need to:
Go to Reports, Balance Sheet.
Choose Period, Ok.
Double-click on Trade Debtor and check the breakdown.
Please ensure there is no amount in 3000/000 (Parent Account).
In case if you have the amount, please check on your last year's invoice and key in the B/F amount under the respective Debtor Account.
Note: The amount in the Parent Account won't be reflected in the Aging report.
