After deleting a specific granular policy, the following message appears:
Showing effective policy inherited from Process Group
restricted-components. Override this policy.
The text "restricted-components" in the message is hyperlinked. If clicked
you get a dialog that says:
Unable to locate group with id 'restricted-components'.
Unable to enter the selected group.
