How to Use and set up links from footer to anchor on page

I am using the Upfront – Scribe Theme and trying to use the Anchor Feature

I have set up Anchor’s on many pages.

But when I am on my Index(Home) page editing the footer, highlight text and go to:

Link > Anchor > I only see ‘Choose Anchor’

I do not see any of the Anchors set up:

Is it possible to do this from one page to another?
