Shortcode Ultimate plugin – Slider disappear

I use Enigma Theme and also Shortcode Ultimate plugin. I use a Slider shortcode from this plugin on the contact page (see link), but it does not display correctly – after some previous updates. When I am editting the page and use Preview, everything is displayed correctly. As soon as I finish editting and use Show page, Sliders are blank (only arrows appear, when move cursor on it). I do not know if problem is in the theme or in the plugin. Any idea, how to display Slider shortcode correctly again?
