Disable Skills & Qualifications Add button from Manager's view

Summary:

Hello Experts,

When a manager tries to see user's skills and qualifications following below navigation:
My Team>My Team>Open Employee>Show More>Skills & Qualification
Few of the sections show Add button, where as some of the sections do not. We have checked the necessary roles/access for the same in
Profile Content Section Access and they all have similar roles & accesses.

In Profile Content Section Access, we have added a custom line manager role to each section and disabled the "Edit Access" in it.
As a result few of the sections are editable, where as some of the sections are not.
