Slider not fully functioning

I really want to make this template work for my site…it’s beautiful! I currently have a problem rendering the slider.

Once I add the slider elements in the WordPress interface, the site (home page with slider) seems to build correctly in the WYSIWYG preview, dynamically scrolling through the slides. However, only one slide is built when the actual site is rendered.

This piece of the code is built:
<div class="sq-slide sq-slide-count1" style="float: none; list-style: none; position: absolute; width: 1018px; z-index: 50; display: block;">…

But the same code is not replicated for sq-slide-count2 and sq-slide-count3 and there is no dynamic element.

I’m using Chrome 48.0.2564.116 (64-bit) on a Mac with Java 8 Update 73. I also tried Firefox with no luck. I suspect something is breaking down with the JavaScript, perhaps when rendered by the browser.

Any ideas?
