I have a project where project admin has created Components, but this system field was not added to any of the create, edit , view screens.
However users are able when bulk changing issues to update the components which are then appearing in the screen. They cannot edit that field but they can see it in the view screen which is not supposed to contain it.
I have even one issue were components is empty and still visible on the view screen.
Is it a specific feature of the Components field? I couldn't find any documentation on it.
