Broken Website on Mobile. Theme Customization displaying multiple errors

Hello

My site was working wonderfully on mobile devices before I updated this plugin. Now, after trying numerous times to fix the issues, I finally have a navigation menu but it does not display my submenus…Instead, a new page opens with the submenus in simple html format. I need them to be styled like a regular menu would. One of the times deactivated the plugin, my site went totally blank on my iPhone, after re-activating it I noticed it went back to the clean styled site, which includes all my short codes, and fonts styled accordingly…Then after refreshing a couple of times, it went back to the new style, which I can’t work with. My short codes are displaying all the HTML text on the actual page and the menu bar is just awful. I need serious help.
How is it that the original site as displayed on FUEL THEMES. If you look at the demo page on a mobile device, it is clean and just the way I liked it.

Please advise. My customers are probably running away scared right now
