Weird display issue

Hi there,

For some reason the plugin is outputting strangely. It seems to be creating two outputs of the same thing. It is rendering the 3-part (html, css, result) window twice. The top version doesn’t seem to factor in any of the shortcode parameters (height, href, etc), while the second one does: https://imgur.com/j5OAe3o.

Any thoughts on why this is happening?
