NextGen Gallery Version 1.8.3 Strange Behavior

I am hoping that someone here has a solution to a very annoying issue. I am working on a site for a client and we are using NextGen for our gallery. When you click on an image you have the navigation bar on the bottom of the image with the arrows but behind it the image is also duplicated and if you click you get the image with buttons on either side. I am not sure if this is a settings issue, a coding issue or something else. You can see what I mean by going to http://precisecustomhomes.com/gallery/ simply click on the first image in the gallery and you should be able to replicate the issue. If someone has any suggestions it would be greatly appreciated.
