Newspaper does not seems to be a default marketing channel. I believe it must have been given this name in Marketing channel manager UI in Analytics. There you can check the rule created for all the marketing channels.
None comes into the marketing channel reports when there are hits which do not meet any marketing channel rules created by you. You can pull out the data feed with marketing channel column like va_closer_id and check the hits with 0 for va_closer_id means no marketing channel rule qualified for that hit.
