Unable to prevent the IC invoice creation

Summary:

We have few sales order types ex: ABC, CDF, XYZ for which IC invoices are getting created because Shipping BU and Order/Selling BU is different.
All the orders are taking "Shipment" business flow and IC AP/AR invoices are getting created as expected.

Now as per new requirement, we need to prevent the Intercompany Invoices on Order type "XYZ" for which we have defined configuration as below

--> Created new Documentation and Accounting rule by unchecking "Intercompany Invoice" option
--> Created new Financial orchestration qualifier with condition "Order Type = XYZ"
--> Created new Financial Orchestration Flow and assigned documentation rule and qualifier
