The System Page header and footer are used on the Error Page 404, Error Page 500, Password Prompt, and Search Results Page

Here is a full list of system page and email templates with the corresponding header/footer group:

  1. Error Page 404  - SYSTEM PAGE

  4. Search results page - SYSTEM PAGE
  5. Email Subscription Preferences - LANDING PAGE

The "Preview" button will only display the marketplace theme defaults because of how the header and footer are being added to the page in the code.
