Migratable Page Composer customizations are not migrated

Summary:

We are currently trying out the Redwood Personalization Helper tool, specifically the option to migrate Page Composer and TDS customizations. I selected all Global Human Resources related modules and imported the received VBS workspaces. I am now performing some sanity checks and I notice that although the analysis states that specific Page Composer customizations can be migrated, it is not reflected on the page.

Screenshot of the analysis showing that a customization should be migrated:

Screenshot showing the applicable active extension rule and the fact that the field is still showing, meaning the customization is not migrated:

The same applies for the other Page Composer customizations listed for this particular page (Hire an Employee) as well as Page Composer customizations on other pages so far.
