The BMV-700 is a battery monitor it measures the current into and out of the battery. If you have battery volts and current and SOC to the battery all is fine.
In this case, the DC load is not actually measured so it is inferred from all other data and is not entirely accurate. See this FAQ describing this.
DC load box calculation if not measured
Do check via remote console that in system set up that you still have “Has DC loads” enabled.
