I am getting these recurring messages in my HomeSeer log for the BL Stat for 2 of my 3 thermostats:

Feb-06 8:43:36 PM Z-Wave Error (2) Sensor Multilevel Report for type Air_Temperature received, but the corresponding device Node ID cannot be found.(2) Node/Instance=19/-1
Feb-06 8:43:30 PM Z-Wave Error (2) Sensor Multilevel Report for type Air_Temperature received, but the corresponding device Node ID cannot be found.(2) Node/Instance=18/-1

Not finding a setting that can help me resolve. Have restarted HomeSeer and thermostats and still no luck. Assistance on a resolution is much appreciated!
