I’ m not sure what versions this will occur in.
There is a limit of 100 price level lists in QuickBooks. In some cases if you hit that number, then delete some lists and add some more, the deleted lists are still counted by QuickBooks and so your new ones won’t show in that report. That is, if you have 100 lists, delete 2, then add 2 more, the report program is still counting those deleted lists, so it thinks you have 102. It only wants to show the first 100, so it leaves off the two new ones (plus leaving off the 2 deleted ones).
