Changes are not being saved properly

Hello,

I’m having some issues with my Divi builder. When I’m in editor mode, the site looks right: my images are the same size/centered, my header background colour and font colour/size/alignment are correct but when I save and publish, the site doesn’t look like what it does in the visual editor.

Could someone please help me out with this?
