New Drag Audio and Video function doesn't shows Multicam audio in source monitor.

The new feature is great, but it doesn't work quite right yet. The source monitor doesn't show the waveform for Multicam in the new Drag Audio and Video feature. However, it sometimes occurs. Repeating a match frame from the Multicam and then from a normal clip several times unlocks the feature. Additionally, the color of the audio tracks in the source monitor could be more subdued. The green combined with the video image is very distracting.
