Multiple instances of the same global classes

Hi, I seem unable to remove the multiple instances of H1-headings etc as seen in the screenshot below. I’ve removed all their styles at all breakpoints, yet they just appear like this. Any idea how to remove them? It’s an empty project, but since I’m already paying for it I don’t want just cancel it and start a new one.

Here is my site Read-Only: [LINK][1]

Thats weird. I’d suggest starting with a new blank project
