Make to Stock Job, for non-Qty Bearing part

A job was created with To Stock demand for a part with the Qty Bearing flag cleared,

The Job was processed w/o any problems, and the part was even “received from job”.
The receipt creates a MFG-STK PartTran entry, but doesn’t show on the WIP Reconciliaton report until after the Capture COS/WIP Activity process is run. And then it shows as MFG-VAR.

Why is Make to Stock an option for a part that is non-Qty Bearing?
