How to remove split on a page?

I have a page which had a dotted line horizontally dividing the page…how do I remove that line? I’m working on Mac OS, sonoma. Thanks

Sounds like the Scrivenings separator. Do you have multiple documents selected in the Binder or a folder containing multiple documents? If so, just select the one you want to edit exclusively.

If you want to merge the two documents into one, use the Documents → Merge command.
