OBSERVED BEHAVIORS:

1. Sliding the Volume fader on an audio bus properly changes both Left and Right channel audio.
2. Double-clicking the volume # (e.g. 0.0dB) on an audio bus and setting the value ONLY changes the Left channel volume!

EXPECTED BEHAVIOR:

On #2, manually typing the volume on an audio bus should set the volume on both L and R channels

Here's a 2-minute video demonstrating the problem

I believe this is a bug. Could someone here confirm?
