Main Menu Problem

I am experiencing a huge problem when using the stock menu in Entrada Modern. Every change to the menu results in submenu items to be displayed as main menu items.
I installed Mega menu but there is another problem (on mobile) the burger menu button opens the burger menu button of Mega menu then when pressing it displays the menu items.

Hello touchp, can you please share your URL, without actually having a look, it’s impossible to guess what you may be missing. Thanks.
Mega Menu is disabled so you can see how it breaks. Most of these items are submenu items and not main menu items.
