A/R Aging is not calculating correctly

It sort of looks like the numbers are off by one box, that 15,410 is current and 2,773 is 1 - 30 days late.

Is this statements using the Intuit Standard Statement template, or a custom template?

If a custom template and you edit it in the Layout Designer, and then click each of the data fields in the aging area, are the fields in the right location compared to the field titles?

That did it! Thank you so much @Rainflurry!! I knew there had to be a box checked somewhere that shouldn't have been...

 My age from the due date is correctly checked.

I made an invoice for a customer today, then did a transaction report with aging checked, and it said they were 138 days past due. Is there anything else to try?

I have some instructions that can get back on track on running a report in QuickBooks, Sandykaye.
