Pack and Ship confirm from mobile inventory screen

Summary:

Hello,

I am trying to execute packing and ship confirmation from the mobile inventory redwood screen. I can search for the shipment and see the items. When I enter the shipped quantity and select the lines to be packed, the packed lines are no longer visible in the screen, only the packing unit.

When I confirm the shipment, and review the sales order in Fusion UI, the sales order lines are still in awaiting shipping. When reviewing the shipment in the classic UI, the lines have been unassigned from the shipment and are in backorder status, with the shipped quantity field empty and greyed out.
