VERTICAL MENU - No Subcategories on mobile devices

Hi Support,

on very small screens no subcategories are shown / clickable with the vertical menu.

I checked it also with your demo side on demo.joomlaux.com/#jux-mega-menu
(vertical demo)
Just reduce the size of your browser (or use mobile) to reproduce that issue.

I does not work on my homepage too. I have a simple menu with text only (no large img or vids)

Can you help me?

Thanks a lot, Thomas
