I can't duplicate that....let me see if I can post some screen grabs....
Seatmap is similar but not identical on those three dates.
There's obviously something wrong there though. Aircraft is listed as:

Aircraft:
- Boeing 737-800
- Capacity: 166 (16 United First®, 150 United Economy®)
- Cruise speed: 530 mph
Likely the reason there's no business class seats "taken".
