Custom Learning Admin unable to edit Course and create or edit Offering

Summary:

Custom Learning Admin unable to edit Course and create or edit Offering

Content (please ensure you mask any confidential information):
Custom Learning Specialist is unable to edit the Course after creating it; the edit button is greyed out. Specialist cannot create Offerings as well while creating a course. If admin creates only a course and navigates to Offerings later on, the Create button is greyed out.

This custom role is secured by Department AOR. Another custom role for Learning Specialist exists which does not have any AOR security profile, and the creation of Course, Offerings and editing is working fine with that role.
