Closed PO available for Invoicing and Matching in AP

We are on 12.2.3.

We have a PO for outside processing that was received fully but not billed  and then the PO was Closed since the vendor would not be billing us..The PO's status shows Approved.Closed but the user is still able to select this PO for invoicing in AP and match it.While matching , Oracle shows a mesage that the PO has been closed you may want to review the PO >If you click OK(the only option) , you are able to proceed with matching the PO .

Just as a test we changed the status of the PO to Closed for Invoicing from Closed but that also doesnot prevent it from appearing in AP for invoicing.
