Sidebar to bottom of page

We have at least 25 Mantra themes working with the Slick Slide show on the home page. All work great except one. If the slide show plugin is activated all the right sidebar (only one) stuff goes to the bottom. Deactivate the slide show and the whole right sidebar goes back in place. I copied an entire home page from a performing Mantra website and made it the home page of the problem website and the same thing happens. Where to look?
