mobile view does not work with elementor in certain pages

Hi, I mead all the pages on my website with elementor.
They are all responsible and works fine with desktop, tabs, mobile view in “desktop”

but when I go to an actual mobile device, certain pages look different. no section, fonts elements appear.

This is the page I made with elementor :

This is how it looks like on the mobile device
( I checked it on another device didn’t change anything) :

Could someone please give me advice on what could cause this issue?

Thanks
