Menu not working in mobile

I′m using top menu and in theme options it is set as resonsive, so it is working as responsive. Now I realised that it creates additionally “sandwitch” type of menu in the mobile. The problem is that menu is actually not clickable. Can I remove it? How? Or in case it`s easier to fix, then how can I remove normal responsive menu for mobile version, so it will not display 2 menus? link is here.
