CSV file "consumed" data MPPT 75/15

I download the CSV file monthly from my SmartSolar MPPT 75/15 but getting 0 Wh in the consumed field.

When looking at the app I can clearly see a figure for Wh consumed data, although this usually returns to zero as the solar panels top up the battery bank.

Is my expectation to see the total daily power consumed correct or is this different to the figure that is being exported to the CSV file?

I’d quite like to see the amount of power that I am using as the SOC % bares no resemblance to the Wh usage I am seeing.
