Hello @joserodrigz,
The given credentials no longer work for us. Please update it so we can check your settings.
By the way, I have back read the previous responses above and I could not replicate the issue. When I check your menu item and its submenu, I am seeing this:

I can only see a two pixel discrepancy here. The actual navbar top height is 107 and in X > Theme Options > Header > Navbar > Navbar Top Height, you have inserted 105 pixels.
Can yo please give further clarifications and maybe send us some screenshots so that we can have the same idea of what is your issue about?
By the way, @Friech mentioned about the CSS because he noticed that in X > Theme Options > Custom CSS, you have inserted a broken CSS code:
@media (max-width:767px){
.x-topbar .p-info{
border:none !important;
}
It is missing a closing } bracket which might also be the case of other CSS that you might have added in the theme.
Please provide a screenshot of your issue and then update the credentials so that we can fully check your site and settings.
Best Regards.
