Nothing is making any sense, found some Broadcast Sheets with either a 1 or a 2 under 13 and nothing else (so far), majority were "2"

Under 14 (ALL A12 cars) I found; 132, 269, 276, 313, 212 (or 218 can read the third digit) 461 62?, 344, 241, and some with NOTHING under 14 and some with nothing under 13 on the same sheet.
