Page inspection tells you have an extra blank anchor inside your top menu bar before your “Home” link. You need to remove it.
The markup you need to remove is <a href="https://www.daiavedra.com"></a>.
The screenshot at http://prnt.sc/ei5h01 shows exactly what is causing the problem.
And http://prnt.sc/ei5hla shows the corrected menu bar after the above item is removed.
Hope this helps.
Well, it seems there is a bug in the theme because that markup was autogenerated. I didn’t add any extra blank anchor inside the top menu bar before “Home” link.
If I use firebug to remove that markup it’s fine, but where should I modify the code to solve the problem definitively? I am not a developer but I can manage some php code modifications.
In that case inside parts/header-main.php there is a function called wp_nav_menu which is most probably preparing the menu for you.
