Creating AR Aging Report in Saved Search

I am getting and error when executing Aging Summary in Saved Search. The only error I am getting is that for the results, there is an invoice that is 76 days (the amount does appear on the current open balance). But it does not fall under the 60-90 Days Bucket. This specific customer has NET 90 Days. When I do the drill down, it does appear as 76 days on the days aging results field.. But I would not know it is at 76 unless I clicked on it.. Any help here? Why is the formula not pulling it into that column?

The Due date, in this case it is set at Net 90 for this customer and it can be for others as I have noticed on my reporting, that is why I believe all the invoices are appearing as "current." When I change the date to a more current "due" date, it does shift the invoice to 61-90 Days. But there is no way I have to do this everytime? Can the formula be changed to just age from Transaction date and not consider if it is CURRENT based on "days overdue"?
