All the templates created using the now deprecated old email editor that were attached to campaigns (Processed, Active and Scheduled for future) have been retained as raw HTML code and will be found in the HTML field of the campaign (2nd Step).
These campaigns will continue to work as intended. If the template needs to be changed or updated for any reason, it will need to be done via the new email editor.
