Melodyne UI is opening in version 14.0.39, however mono signals are being forced to left side.

[originalskid]

In the 14.0.39 build the GUI will open but it is supposed to show all the selected tracks in one window in order to set a reference track to align the other tracks to.
I have tried assigning MTrackAlign to single tracks, multiple tracks at the same time, single clips and multiple clips at the same time but the results are always the same.

The logfile shows "ARA plugin does not support time-stretching - hosting in pass-through mode"

Here's the entire logfile:

This sounds like a bug in the plugin as if you have multiple Melodyne instances on different clips, you can see them all in the side panel of Melodyne.
