After opening a Live-Set where I use the Laboratory in Sound-Mode, browsing the library with CC 20/21 assigned to the controller, loads scenes even if sounds are shown.
I can switch between UPPER and LOWER channel of the scene, using the UPPER/LOWER buttons on the keyboard, in sound-view.
I have to switch between sound- and scene-view before I can move through the sound-library again, or use the mouse to click on another sound-preset.
The same happens to the standalone version, when Sound-View is on after startup!
