The new Level Visibility track creates a Visible track that appears that it is created in the middle of the sequencer tracks.
You are able to move the Visible track up flush with the timeline by clicking and dragging.
This is a regression from 4.14.3
Result: The Visible(0) track is not flush with the top of the sequence
Expected Result: The Visible(0) track is create flush with the timeline
