I am having an issue with the "move" feature in the Layer Designer -

Let's say I want to have have a green-screen background for Talent. I create a blank Virtual Set. I have a PNG asset on layer 1 acting as a background, and a Chroma Keyed Camera Input on Layer 2. Both layers take up the full 1920x1080 frame. Now I want to "move" the Image on layer 1, so I select layer 1 (highlighting the "1" in Green and showing me the "move" "crop" "border" options for layer 1). I click on the Preview Window below, hoping to be able to click-and-drag the image on layer 1 into a new position- but when I click on the preview window (with Layer 1 selected), it instead activates Layer 2, and now I'm dragging around my Camera Input.

Any idea what is causing this or how to prevent it from happening?

FWIW, I understand that I can move the asset in Layer 1 by clicking the "Edit" button on Layer 1 and tweaking the XYZ axes from the "Position" tab- but it would significantly improve my workflow to be able to make these adjustments in the "Layers" tab where all of my Layers are visible and quickly navigable in one place.
