Then something of that plugin has remained there. Look again and make sure you have indeed removed it. Even remove (copy) all your plugins and start by adding the "know ones" back (and always restarting SU).
When you create a scene with a new or modified style do you get this message box?

If you don't, go to Window>Preferences>General and tick the box for warning you of style changes.
