Where is the header text stored?

I changed the name of my book, but the old title is placed for header text on every page.

I need to change that but for the life of me I cant find where to do that.

Project → Meta-Data Settings → Project Properties → Project Title

How about on a Mac? Using Version 3.1.5 (12258), Mac Catalina OS ? I’ve renamed the *scriv file but the original title stills appears?

Perhaps ask on the mac part of the forum.

That’s probably a really good idea.
