I up-dated to v10.37L build 18 last night, and in the high & low boxes for Extra Sensor 3, the data is being displayed in scientific notation (see attached shot). The value for High reads 8.50000000000000E+001% and the Low value is 7.70000000000000E+001% (85% & 77% respectively).
Also, clicking on RESET had no result.
Cheers,
Ian
