only see an icon with arrow pointing out and it doesn’t show any links

I only see an icon for outbound links (arrow pointing out) and it doesn’t show any links for any posts or pages.

I looked on a page and it says:
No internal links appear in this page, consider adding some as appropriate.
This page has 0 nofollowed outbound link(s) and 5 normal outbound link(s).

4 of the links are pointing to pages on the same site. I use Multisite with subdomains.
