Sinatra Theme menu duplicate issue

Hi,

The menu has duplicated, although I did not create nor add extra menu. Also, the menu was on top where I want first had it, however now it to the side-left and enlarged with bullets. Between each menu are a big 3-layers of lines, and big + sign to the right of it, and between the duplicate menus.

I’ve already cleared cache on browser and on the site, plus deactivated all Elementor plugins… added them back one at a time, and also deactived the Sinatra theme, and then activated the Twenty-Two Theme.

The page I need help with: [log in to see the link]
