There is extra black space above the audio track in the Edit and Fairlight pages.
Is there a way to hide it?
This is because [View]-[Show Audio Track Layer], which is used in an editing method called audio layering, is enabled.Try unchecking [View]-[Show Audio Track Layer].
Audio layering stacks multiple audio clips on one track, and if there are audio clips on the upper layer, the audio on the lower layer is muted.
For audio layering, enable [Timeline]-[Layer Audio Editing] and [View]-[Show Audio Track Layers] to display the audio track layers within the track and overlap them. It will be possible.
