I have a React, and it should only display values for the sensors that are actually connected...so I'd guess you've gotten some moisture in the transceiver. The Nomadio transceivers are delicate little things with a lot of openings in for plugs, so it's a good idea to protect them any time you're going to be running in wet conditions.

If it's not the water, then i guess it could be a faulty transceiver, but if it continues to do it then it might be worth re-flashing the software for both transmitter and receiver. This might fix it.
