Product Gallery Images not shown as thumbnails

Hey guys,
I just updated the Unicon theme to the newest Version today together with the attached Visual Composer Update, but unfortunately now all Product images on my Product Pages are displayed in full width which looks very disturbing. I’d really like to have the standard view back with the small thumbnails under the title image.

You can get an idea of the problem here: http://www.staging.xn--minikchenonline-3vb.de/?product=ninja-silhouette-2

I hope we can get this fixed!
Thank you so much! ;))
