Issues with New Video+Waveform View

Having a few issues with the new Video+Waveform view in the Source Monitor.

1/ The button doesn’t seem to work for Multicam Clips. It’s greyed out (see image). Only selecting split view in the wrench menu works.

2/ Cycling through clips in the Source Monitor behaves erratically. Sometimes remembering which state a clip’s view is set to, sometimes not.

3/ Sometimes the waveform IS displayed behind the video - only on Multicam clips so far (see image).

Tried resetting prefs - no luck.
