everting back to its old hedings

Hi I’ve having trouble with this all week, it keeps going reverting back to its old headings when I go live but it goes back to normal on when i edit it

I’m not an expert in the program yet, but I’m just chiming in to make sure you’re pressing publish (top right) to make sure the changes get pushed online?

What is your website url? So text is keep reverting to default one?

While you are logged in, no need to hit publish in order to see changes on live website. You as an admin always see the most recent version. Publish is to go live for all other visitors.
