Revenue Report Still Buggy? Cannot list Last 60 Days Sales

I'm reviewing sales using the Revenue Report. If I choose:

Order Status: Please Select
Set Internal: Monthly
Set Period: Last 60 days

Then I see results.

But if I set the filters to:

Order Status: Confirmed
Set Internal: Monthly
Set Period: Last 60 days

The I see no results, which does not make any sense. I should be able to see 'Confirmed' purchases within the last 60 days.

How can this work correctly?
