Help with multiple audio outs desktop

I am trying to use the standalone app on Mac with multiple audio outs. (UA Apollo quad with Expert Sleepers Es-3) although I have the 32 out audio output module in the rack the only outs that are working are 1&2. No audio (or CV…or anything) is being passed to other outputs. Is there an audio device configuration setting somewhere like in VCV rack?

UPDATE: it works properly with the 16 audio output channel module…32 it still does not. I think there must be a bug in the 32 audio out channel module
