VESC not reporting ah charged or wh charged

I am trying to collect some data from my VESC and for some reason it is always reporting that ah charged and wh charged are 0, despite the fact that I am able to use regen braking and both the motor and battery current are negative while I am doing so. Does anyone know why this might be the case? I am using firmware version 5.2, hardware version 4.12, and VESC tool version 3.00.
