In ASCP, how to use substitutes supply but prevent planned orders for substitutes

Using EBS/ASCP version 12.4.2. We are actively using substitute components in our BOM's and planning the same in ASCP. With the current settings in the profile options and plan options, ASCP is correctly netting the substitute components, but in some cases creating planned orders for the substitute components as well. The expected/desired behavior would be for ASCP to continue to net the substitutes but ONLY create planned orders for the primary BOM component.

Plan options include: All Planned Items on the Main tab, Use Substitute Components on the Decision Rules tab, Constrained (With Detailed Scheduling) with Enforce Demand Due Dates ON and Enforce Purchasing Lead Times OFF.
