BMV 712 shows voltage but all other information is at zero (current, power, consumed Ah)

My BMV 712 shows the correct current (both with batteries connected and when connected to shore power), but the Current, power, and consumed Ah are all at zero. It doesn't show power going in or out when I do some experimenting.

I have 2 12v lead batteries in parallel. I am using only the B1 power source for the BMV.

Ideas as to why it is not showing information other than battery voltage?

How did you connect the BMV 712?

What is connected to the negative terminal of the battery?

Do you have a wiring diagram or link to one?
