Create PersownWantsOrg via Process, but request properties not added

Hi 

I am trying to create a PersonWantsOrg record via a process task (HandleObjectComponent - Insert). When I create the PersonWantsOrg record this way, the "calculated" request properties don't get added to the request?

When I request the product via the web portal the calculated request properties are added.

My request properties parameter type is "calculated" with my Value Calculation being set to the column i want.

I am using 9.1.1 - Angular portal

thanks in advance
