How site published with obsidian reacts to ahrefs audit

Hello, I’m trying to solve ‘an SEO problem’. I published my site mjl-tek.net with obsidian, and submitted it to ahrefs SEO audit.

The ahrefs audit says that all my pages are orphan pages (has no incoming internal links).

I’ve checked the site map, that’s ok.

Example:

Welcome to mjl-tek.net - mjl-tek

links to

The Trusted System - mjl-tek

But ahrefs still considers it (the post linked to - Trusted System), an orphan.

Can anyone shed light on this?
Perhaps I should try a page without spaces in the title?
