Sorry about that. 
I think we have an open ticket to sort that out.
Out of curiosity, could you check whether using the ‘replace text’ button on your /admin/customize/site_texts pulls the latest version in?
Update: Checking in on it, I think it was fixed by this a couple of weeks back:
https://github.com/discourse/discourse/pull/25505
I think that should make the ‘replace text’ a more solid option. 
These are dependant on having the company name admin setting filled in. If you haven’t done that yet, could you fill it in and see if that gets them to appear?
