Energy exported and consumed are the same

[Not sure where this is coming from, maybe from myenergi itself?]
My energy company does not "net phases" and calculates both consumed and exported power at the same time, if phases are out of balance.. For example, if I am:

1. exporting 2kW on phase 1
2. exporting 1kW on phase 2
3. importing 4kW on phase 3
   My energy meter will treat this as 3kW exporting and 4kW importing at the same time.
   When I set "net phases" to NO I expect the same behavior.

However I am getting identical negative values for importing and exporting power, even though there is a huge disbalance among phases (solar inverter is running on 3 phases and boiler running on one phase). See picture.

It needs to be a vector sum of the 3-phases not a simple arithmetic sum. So the PF or phase angle of each needs to be used to achieve the vector sum.
