I have 400ah of lithium batteries.
Power used is just a couple of tape strip lights, mini fridge and vent fan. Including a photo of the monitor reading now.

From the picture it's drawing 3 amps, so you definitely have a small load on the battery.
The Shunt is a mystery. It should be right at the negative terminal, and no load returns (negative wires) should connect to that except through it, otherwise you're not measuring all the current used. Is that the case?
And this is a 12V system, correct?
And your diagram has three batteries, but I only see two in the picture. The shunt is either incorrectly captured in the diagram or improperly wired because the charger appears to be connected to the negative terminal of the battery (in which case the charging will not be registered on the shunt).
I recommend you physically check voltages-go get an inexpensive multimeter if you don't already have one and watch Ross' video if needed. Check the actual voltage of the system to make sure there's not something else interfering with the voltage readout on the monitor.
