Adding components in editor is different than live version

I have as you see in the image built some kind of form where the user can insert an image or a text, video…etc

in the editor when I preview the webapp (both in desktop and mobile views), the components push the footer down if they are added (which is what I want), however in the live version of the website, it acts naturally on desktop, but on mobiles the footer is static and the added components by the user go behind the footer,it’s driving me crazy, I have tried everything I can, thank you for your help!
