They’re called ‘published pages’. Though your Privacy Policy and TOS should already be doing that automatically if you have them set (like ours Terms of Service - Discourse Meta, Privacy policy | Discourse - Civilized Discussion)
You could check you have a company name set in your admin settings. There was a recent change to require that. It shouldn’t have affected existing sites, but if you made any amendments to that setting recently you may have caused your TOS and Privacy pages to become ‘unpublished’.
Or you could also check your tos url and privacy policy url settings to see if you’ve add the topics themselves to those, which could override the default published ones?
