How do i layer the tracks in timeline to make audio spectrum filter visible over the images?

Cannot view Audio spectrum on video track, until other video track is disabled.
Please check the images below for more clarity.

  1. Audio spectrum visible with Image (video) track disabled -
  2. Audio spectrum not visible with Image (video) track enabled -

I believe that the audio spectrum track’s compositing setting should be set to a single square, not three, like so: (here I’m recycling a three-track compositing example)
