Revolution Slider Issue?

I’m not sure if this is a bug or my own error, but when I scroll down my page, instead of the parallax effect, I see a grey area at the top of the revolution slider instead of my continuing image (see screenshot). I never changed any sizes in the settings menu and as you can see I inserted the demo slide and it still did this so I don’t think it’s a size issue. I also went and took another look at the demo site and I didn’t see this happening. Any suggestions are greatly appreciated. Here is the website, it’s a temporary URL: http://69.195.124.220/~synergyn/
