I2C ADS1015 settings not working

[ragbagger]

Openplotter 3
Openplotter-i2c 3.3.12
Rasp pi 4
ADS1015

Openplotter-i2c recognizes the ADS1015 and brings up settings.
After adding signalk key and ok the signalk data for that key is "null"
If "add raw data" is checked data is shown in signalk.
No other settings on the dialog appear to do anything.
The settings window has self populated with: "Range1 = 0|1700-> 0|16" with no other info.

Thanks,
Brad
