Problem with routing in Ableton 12

[Symptom]

I want to set up Output Type in Return Track but there are no Group Tracks available (only Audio Tracks are visible in the list). This is what's happening in a new project in Live 12. In my old template from Live 11 everything works as it should. Anyone have the same problem?

You're probably mixing things up, it's no different from L11 in this area.
You can either route to an audio track inside a Group Track, or use a M4L device like this one to grab the audio from a Return directly in the group track's devices' chain.
