cdj400 aggregator issues with djay pro on mac

Hello. I’m trying to use my two cdj400s and djm 800 with djap pro for Mac. But when I set up the cdjs as an aggregated device I Dont get any audio output through the cdj into the djm. They are already midi mapped and work to control the software. But I can’t get any audio out this way.

But if I set one up as just a normal USB midi/audio card I can get audio out through one cdj. But I can’t set them up to control separate decks this way.

I would prefer to use them as an aggregated device. So if anybody has run into this issue, or knows what is going on, could you please help?
