Video Clean Feed missing after update

I just updated to Resolve 17 and my Video Clean feed option disappeared.

Running on a 2013 iMac with Nvidia GeForce780M GPU. Had to upgrade from MacOS High Sierra to Catalina, which disabled CUDA (at long last, I had been hanging on to High Sierra as long as I could), but Metal seems to be working and Resolve is otherwise functioning perfectly. Have a second 27" monitor hooked up via the DisplayPort.

I have searched high and low but can't find a solution that works for me.

What am I missing?

The issue has been resolved - the update to Resolve17 turned out not to be the studio version (I'm not sure how this happened as I was running the beta previously) - I uninstalled and reinstalled studio version and all is well in the universe!

Studio?
