Melodyne Studio "Editing Mix Fader" doesn't work with ARA

I came across this today as I was exploring features that are new to me since upgrading to the full version of Melodyne.

When playback is started from Melodyne and not Pro Tools, by double clicking at the top of the Melodyne ruler, the three fader positions indicate different behavior:

Far left: Only hear tracks being edited (orange)
Middle: Hear tracks being edited in addition to tracks selected as reference tracks (grey)
Far right: Hear tracks being edited in addition to tracks selected as reference tracks and also other tracks that are actively being Melodyned

This works as expected with the plugin version, but in ARA the mix fader does nothing. I'm not sure if it intended to be integrated into ARA, but needless to say it should work as expected or be omitted. That slider doing nothing at all in the Melodyne Studio ARA UI is confusing. Can anyone confirm?
