One other serious error in the site is that you have added a menu item without link which is causing a Javascript error in certain situations and can lead to unexpected behavior like sticky menu not closing.
I thought it was not possible in WP menu to add a blank menu with no link but looks like we can blank out the URL of the menu after adding to the menu (otherwise, a link is a must for adding a menu item). Can you please input a URL for the Recursos menu link – probably to a default page. That will help get rid of this error.
