Having problems with the mobile menu - mobile menu not showing

Hello guys.

I have recently bought GP premium, and I have been building my first website with it https://mauriciobautistadev.tech with hostinger, I'm planning to migrate this website to my father's hosting and domain at http://frcingenieria.com with GoDaddy, and then build my portfolio on my own domain.

After using the GP native mobile vision and my real phone to see the page, I have confirmed that the menu on mobile version does not work that well, since it doesn't show any of the elements I have added, such as "nosotros", "productos, "unidades de negocio", "contacto".

I deactivated all the plugins, cleaned my cache, but still don't know what happens.

Thanks for any help you could give me.
