Report Picking of Zero On a Line in Shipments and Still Delivers Line as Picked??

Has anyone encountered the scenario where there are order lines tied to a shipment and instead of disconnecting the line from the shipment, you report picking of zero (0) on a specific line.  The line is still tied to the shipment and shows 0 picked after reporting picking with a quantity of 0.  When you go to finalize the shipment, selecting ONLY “Picked Quantity”, it still delivers the line as if the quantity was actually picked!  See attached for example.  We’ve tested this scenario multiple times and come up with the same result.  Is this a bug within the Shipment module or are we missing a process step?
