Wordpress [Elementor]. Displays the main menu incorrectly. What to do?

Question

WordPress

Good afternoon!
I'm setting up the main page of the site koli-bri.ru through Elementor and I can't figure out where the error is.
I go through WP - everything is ok:

I save, I look at the page without the admin panel, the top menus float:

The top headers and menus are EXACTLY THE SAME as on the subpages, but for some reason on the main page everything goes wrong, as it should be ..
Thank you!
