I put a checkmark in the "Except zero Amounts' check box, but the report still prints with an extra row beneath each Expense Account  line that includes sub-accounts. If an Expense Account does not have any sub-accounts, then there is no extra row beneath that line.  On screen, the report looks fine, with no extra rows. But if I print it or "Save as PDF," the extra rows are inserted.  Note that the "Collapse Rows" button has been chosen.
