The reason this is happening is because the entire line is not blank. You still have iTicket_ID on that line.
One trick is to put some print when logic on iTicket_ID to suppress it if Problem and Resolution are both blank. Then add iTicket_ID again on the 2nd line and put logic that is opposite so it only prints when both Problem and Resolution are blank.
