Just to be sure, when using Show Components In View, you did select the view as well as the components you wanted shown, correct? Next, try View Dependent Edit, select the view, then press Delete All Edits. If that doesn't work and you're not seeing the background of a section cut, you need to edit the view style and enable the background for the section cuts.
