Clarification: those specific books are usually painted green but upon re-scan on next use they are again reverted to yellow. When I compare metadata what usually happens in these cases is a mismatch in publication dates: the field in Marvin is 'unknown' whereas the field in calibre is either a logical date or something nonsensical: 1st January 101...
