Particle TrackLength with command based scoring - all zeros

Geant4 Version: 11.2.0

I’m trying to record the track length of muons inside a given volume using command based scoring.
What is the reason for this outputting all zeros?
I have visual confirmation that there are indeed a lot of tracks inside the volume but the file has all 0s on it.
