Problem with moduls JS Social Slider and Jux Mega Menu

I have problems on my homepage www.kant-ingenieure.de with the combination of the modules JS Social Slider and JUX Mega Menu. I am assuming this is a JQuery problem and I have already tried with all possible variants of jQuery Easy.
The menu item "About us" no longer shows the corresponding formatting. I'd be happy for help.
