You can still read those responses as Editor, they’re just not included when composing a message to the Author. If you want them to be available for inclusion in the message to the author, you’ll have to modify that form element in the database; see the included column of the review_form_elements table. We don’t permit modification of the review forms via the interface once they’re active, as this affects the record.
