Shortcode on Revolution Slider

Hi, trying to display a shortcode on top of a revolution slider, to add a login button for our welcome splash page.

We had it working in a previous version of the site here,, using the code <div class="interfacecontainerdiv">[LoginRadius_Login]</div> (see screenshot).

Now when we do the same though, it's nuking the slider:

It seems like it has something to do with an update for the plugin and/or theme, although trying to figure out how can diagnose or make work otherwise!

Thanks in advance,
