HEM2 Shows Voltage in KWH graph

Im struggling to get datamine2 show KWH usage with the HEM2

The KWH in Vera UI shows correct value, but in a blink it shows 230… voltage

When I read the Datamine graph it show 230 all the way until suddenly it shows the actual KWH for a minute (attached)
Why is that?
The KWH value for each phase is shown correctly
