Vesc 6, FW 5.1, WH charged is not being logged

I've been using 4.2 before, and it logs WH charged just fine.
This is strange, because after running RT logging and downloading CV, it DOES show regen current just fine, but wh charged fields are empty. Wh used is being logged.
What gives? I'm using the VESC is a pedal generator, and in fact I've bought version 6 exactly because I wanted better accuracy (that is claimed as one of Vesc 6 advantages).
