Transportation Ship Confirm for SO Fetches PO Lines

Client is running JDE Transportation Management, and upgrading from OneWorld Xe to E1 9.1.  On Ship Confirm, when we click Row > Confirm > Confirm Shipment, the system goes to a form labeled 'Purchase Order Receipts - Fetching Data Rows'.  Since there are thousands of PO rows in the system, it takes several minutes for this form to execute.  So we click the 'Stop and View Results' button on the form, that takes us to the 'Purchase Order Receipts' form.  This form then has a 'Record Invalid' error, so we click CANCEL on it, then we go to the 'Shipment Confirmation' form.

On the version of P49645 that is called, we have a '1' in Option #12 on the Process tab: Process Interactive/Batch Shipment Confirmation.  We have #13 on the Process tab set to 'blank', this is Process Purchase Order Receipts.  We were thinking that these were the correct settings for calling SO ship confirm, and NOT calling PO receipts.
