Unable to edit grant scope for Roles in org

I’m currently trying to assign users to my Boundary environment. From what I understand about grants, principal access is granted at the project role. So even if a user has

id=;type=;actions=*

access, they can’t see any targets created in a project unless you specify the scope for the role.

The issue I’ve found is I’m able to edit the Grant Scope in the UI

However if I save this, it doesn’t actually change the scope and still defaults to the Org:

I’m editing this through the default admin user account. Am I missing something
