Not seeing seperate outs from Analog RYTM in Ableton

Hi,
I’m not getting separate audio outputs from my analog RYTM Mk1 in Ableton using Overbridge. I’m getting the main outputs on the midi channel where the Overbridge plug-in is active and the separate outputs come up as an input routing option on the audio track but there is no audio.

Mac OS 10.13.4
Ableton v 10.1.7
Overbridge 2.0.31
Analog RYTM Mk 1 OS 1.50a

Cheers.
