Mobile responsiveness issue with hello theme

Hi,

I’m having trouble seeing two pages of my website correctly on the mobile version. it happened from one day to the next so I guess it must have been some update.

I have no idea how to solve it, so I would really appreciate some kind of help.

the problems are in my home page

and just at the checkout page of my online store https://boboespazioa.com/tienda/carrito/finalizar-compra/ (desktop is ok, not mobile)
