New Energy Monitoring -- import vs consumption

Hi all.
Im a little confused RE the energy monitoring.
The UI states use a sensor for consumption from the grid, however i think what its actually looking for is overall consumption.

At the moment i have mine setup with only power imported from the grid, ie energy i use that isnt solar generated, and i believe its messing around with the numbers

The sources all seem correct, but the graphs dont.

The self consumed graph seems right, but the returned to grid is potentially not - Its showing returned MINUS imported — ie the net overall difference. Is that as designed?
