It looks like the HTML is broken. A section could not be outputted inside a section when using builder controls only.
I’d recommend that you save your page as a template and then load it to a test page and remove elements and sections one by one to see what section is causing the issue. If you’re not familiar with saving a template, please see the Template Manager documentation
If there’s no broken HTML in your page, please give us WordPress Admin access in a Secure Note so we could check your setup.
