Purchase Order Print PDF shows incorrect results after line cancellation

Content

When we print a PO PDF in Approved/Open Status, it shows the details in proper format as per customer requirements.  But when I cancel a line or the entire PO, the PO PDF shows the lines incorrectly. The open lines show up twice and cancelled line show up 4 times. We have customized the PDF based on customer requirements, but not included any logic for cancellations. Please refer attached material and suggest what could be causing this
