Max For Live Tuning System not returning valid LOM id

Dante's icon

Is there a trick for reaching the LOM's Tuning System?

A little tick box in the settings or something that i'm missing.

I've tried setting the path "live_set tuning_system" but always returns id 0

Same with the built-in M4L snippet M4L.api.ObserveTuningSystem
returns id 0

same here... maybe a bug ?
