PowR3 readings seem to be wrong

I’ve just bought a couple of POWR3’s. I installed one a couple of days ago to control the power to my workshop and to see how much power I’m using. Ive just had a look at the consumption and it seem to be wrong
158.81 / 247.63 = 0.64A not 0.97 like it’s displayed
I’ve checked the voltage with a multimeter and that is displaying correctly.

The device detects the Real Power instead of the Apparent Power.
See the below link referring to Real, Reactive, and Apparent Power.
