Meteobridge not letting me change sensor

[rts007]

I have an Oregon Scientific WMR968 (yes, I know it's ancient). I added a new sensor (Thgr968) and I set it as the Outdoor temp in meteobridge yet PWS weather, wunderground, etc are still showing the previous sensor's readings (thgr122nx) instead of the one I selected. I've reset all the sensors, the main unit and the meteobridge to no avail. I'm stumped.

Update: now I can change the sensor, but the humidity and dewpoint are not being reported to the various online services. Weird!
