Slider revolution seems to break media query for divs below it

It seems that any <div> after the slider loses the ability to become responsive. The media query that is supposed to add “.responsive” to the flex_columns and turn off float, etc. under certain screen widths is applied to the <div>’s above the slider but not below the slider. When I remove the slider from the page, then all the <div>’s behave as expected.

I am working on the two following pages.
Content is nearly identical and so it should help illustrate and troubleshoot, I hope. (See private content section for links to our staging site)
