Featured Item displays image twice

I can only get portfolio items to appear on the Preview page by setting an image as a ‘Featured Item’. However, this causes 2 large images to appear in the portfolio page when I only need it to appear just the once.

Is there a way of listing new portfolio pages without setting an image as a Featured Item?

I am using the Commander Theme v1.0.1
