Editing for mobile

Hello, I'm editing the mobile version of my page currently and everytime I move anything in any way it adds space and send all my content to the bottom of the page. If I try to move the content back where it was originally it just spaces the other content out even more. Everytime I put something in it's spot it moves everything else. How can I avoid this or what is a solution to this issue. It seems to only happen on some of the pages not all of them.
