I doubt that it is NOT the right one... it's either not set up right in the module, or you have a set selected, or Ride selected that is not a 3-zone ride... you have to look through, and try, all the rides, and you'll find some that are, and some that are not.
Make sure your settings are for 3 zones, and that your cables are all correct.
I can't give you more info, because my module is not here, sorry...
