How do I control wall shading showing, (or not), in window openings in a view?

[vanderloo5]

What determines whether the fill in a wall style shows in a window opening or not? Some windows have no shading, (as I would prefer), and one window has shading going through it. Can't seem to find anything in graphic overrides.

It could be that you have a duplicated wall at that location. Either in your model or in a link.
