Missing Master Channel

I'm missing my Master audio track all of a sudden. I can see Bus 1 only. I did a clean install of Resolve Studio, still didn't work. This happens even when I create a new project, it defaults only showing bus tracks, but no Master audio track.

What can I do to get it back?

Thanks!

Resolve 17 enables Flexi Bus mode by default providing more flexible Buss to Buss routing.

With a blank Project prior to using the "Create New Timeline" command, enable the following preference to enable the Fixed Bussing structure of Resolve 16 and prior:
Project Preferences > Fairlight > Audio Busing Mode

Refer to:
Resolve 17 Manual | Page 3163 | Chapter 168 | Setting Up Tracks, Buses, and Patching

Reynaud, you are the frikin MAN. Thank you!
