NO Global Theme Header and Footers

Hi, I don't seem to have the tick box: use this area as a global theme header. Is there an option to do the same with footer as well?

I've built this theme from scratch with the Upfront Builder, this is the first time I've used the software. I can't see an obvious way to make the header and footer truly global i.e. not having to manually add the header and footer to every page - it should just automatically be added to every page and post.
