Unable to See Finally Close Shipment Line

Dear All

We are testing a PO Closure functionality. What we did is as below

1. Create new PO, Invoice Close Tolerance 0%, It's 2 way match and Invoice match option is with PO. Only 1 line and 1 shipment.
2. Matched the full Quantity while entering Invoice and selected check box "Final Match" in PO Match window
3. This should change the status of Shipment to "Finally Closed"

Now my question is, when I open the PO and check the Shipment line, I cannot see the line 1. Instead of that I see just a line No 2 and rest fields are blank. I just want to see the PO Shipment. We are aware that Finally Closed PO can not be re open and we do not want to open it. We just want to see the PO Shipments on the screen.
