Very old purchase orders are "cancelled", "closed", and "In Process", how do I change the approval s

R12.2.5 Purchasing

In 1996 on a prior version of EBS, POs were created and are now in the state of being closed and cancelled, but the approval status is stuck in "In Process" and I can't seem to change it.

Buyers often check the status of document approval by using PO Summary --> Status --> Approval Order "In Process" --> Find, as shown below:

But due to this old data in the result, they have to sort through it and ignore it every time.  These old POs will not query in the PO entry form.  Is there anything I can do about this through the application or is it appropriate to open an SR and request a data fix?
