Number of overdue invoices doesn't match

Is anyone else finding that the "Overdue Invoices" section on the dashboard doesn't always match when you select it?  I am finding that it is including invoices that are due that day so they actually aren't overdue until the next day.  Today our shows 6 overdue but 4 are actually overdue and 2 are due today.  Happens often.

Also when we do statements early in the morning on the 1st of the month the "ageing" doesn't appear to have happened, as if we run them again later in the day the current, 30, 60 etc days can change.  Can anyone tell me what time we need to wait until?  We thought these calculations by MYOB would happen once the date changes at midnight, but it doesn't seem to be the case.

Thank you.
