My posts that I added a featured photo to are now showing up twice.

I just uploaded the Custom Community today and love it! However, for some unknown reason when I added my four most recent posts to the slideshow with featured photos they now appear twice on my front page. I reduced the number of posts to be visible down to 4, but it still shows all of them twice. I have VERY limited coding ability and have no idea what to do. Any and all help resolving this matter will be greatly appreciated as I really do love the theme. My website is http://www.lifeingames.com
