Unwanted Guidelines empty link in the about section

Hello everybody,

I want to configure urls in the about section of my discourse forum. (Version 2.8.0.beta10-b75cbec4b6)
I go to the admin section → Settings → Legal

There is see 4 settings : tos url, privacy policy url, faq url, log anonymizer details

Adding an url to the first one “tos url” works perfectly.
Same for the privacy policy url.

Problem:
But when adding an url for the FAQ url. The FAQ link work as intended in the about section. But discourse created a new section Guidelines with no link (cfr screenshot). I didn’t ask for this guideline link to pop from nowhere. I don’t see anywhere to set up a link for these guidelines. And I’ve now a bugged Guidelines link in my about section.

This empty link disappear if I discard my changes and put an empty FAQ url in the admin setting.

Is this a known bug, or did I miss something in my settings / config ?

Thanks by advance !
