VR Controllers don't track with Left Handed Mode enabled

I have the Steam version of Substance 3D Modeler 2023, and I can run it in the default Right Handed Configuration.  However, if I enable Left Handed Mode, when I start in VR, the controllers are stuck at the 0,0,0 location.  There is no tracking and the buttons are unresponse.  Being left handed, the app is completely useless to me.  If anyone else has encountered this, were you able to get it resolved? And how?
