Editor not reflecting front end

On this page, you’ll notice that the “Car Washes For Sale” featured content slider plugin appears above the “Crystal Clear…” div. And that’s what you see with firebug too: https://www.screenshots.cc/show/55535/y6w4m.

However, in my page editor, I have the shortcode for the plugin located below the Crystal Clear section. See this screenshot: https://www.screenshots.cc/show/55534/644yd

So why does the front-end not reflect the way thing are arranged in the editor?

Please advise. Thanks in advance!
