  3.  Choose Remove.
  4. In the remove role assignment message that appears, select Yes.

As the inherited role assignments can't be removed, you have to do it at the scope containing the created role assignment that consists of a link which can take you to the scope where this role was assigned. You can easily remove the role assignment by simply going to the listed scope.
