Outated certificates help page

The actual certificate edit form on a title (e.g https://www.imdb.com/title/tt36460578/parentalguide/) allows for different inputs. For example, one can add Canada:(Banned), but this doesn't appear in the help article https://help.imdb.com/article/contribution/titles/certificates/GU757M8ZJ9ZPXB39 and i would assume there are more cases.

If it's unlikely the help page will ever be always up to the date with the form, then at least the help page should be more clear that those are just examples and the actual form contains additional options.
