If Battery C needs to be charged, and the charger is turned on, it indicates charging amperage. However if you switch panels in 2D and return to MDC3 it reads zero. You can turn off the charger and back on and the current comes back up but the behavior is reproducible.
The behavior does not exist in the VC or when going from external to 2D view. Additionally it appears looking at FC flows that the charging stops after the panel switch, not just the display itself.
