Battery Monitor 2 >> "Amperes per Volt" empty

I have the same problem. I’m using:
Cube orange
(2) Mauch HS-200-LV sensors

In the Arudpilot configuration instructions: it is clear how to setup the firs battery monitor, although options have changed. I’ve now selected to use CubeOrange:

However, when I go to setup Battery Monitor 2, the options are different. for “Volt pin,” I now have options for CubeOrange, which I have selected. However, above it, and by default, “Pixhawk2_PM2/Cube Orange PM” was selected upon adding the 2nd battery monitor. Should I have changed this? I noticed the current pretty doubled when I did…

When I enter the values (as shown) according to the instructions for “voltage divider” and “amperes per volt” it accepts them, but then when I shut down the flight controller or reconnect, the amperes per volt is missing. Am I doing something wrong?
