I am seeing this in MacOS Mojave as well (10.14 beta (18A326h))

Is this still not working?

Still not working for me either (High Sierra 10.13.6)

However, you can make a workaround for now as I did. I mean, go to Preference Pane -> Shortcuts and set up a shortcut for Do Not Disturb. Then you can invoke it from BTT.
