Destroyed CSS because of the color-section in product-category page

Hi guys,

I’m working on this page: http://redesign.meinrollgeruest.de/kategorie/roll-standgerueste/gerueste-mit-fahrbalken/

As you can see, everything seems fine until you reach the bottom of the page. The footer looks damaged and the CSS is different. As comparison, here’s another product category page, where the footer looks fine: http://redesign.meinrollgeruest.de/kategorie/roll-standgerueste/rollgerueste-mit-auslegern/

I found that the color-section causes this problem. As soon as I put the code for color-section: [av_section xxx] lorem ipsum [/av_section]
the CSS for footer will be destroyed. What should I do to solve this problem? Color-section is an obligatory and required to set the right padding, background color, etc.

Thanks in advance.
