I can't see any <div>'s that it is under? I checked the main sheet and can't seem to find any adjustments to wowslider html5... it seems as if it's placed by itself without <div>'s?
It has to have Divs Mat. This is Steve's test site and my site both using WOW slider but if you can see the divs there.
