Help Regarding Map Sound Editor

[DoubleG01]

Hello! Recently I've been learning some about the world sounds and using the map editor / sound editor to add different sounds to a map project. I can load up the sound editor without any issue, and can place a sound item, but there aren't any nodes visible on any of the sound items in order to move them or edit their properties. I've double checked everywhere I can think of, in the visibility options etc. and can't seem to get any further than placing a sound item in the editor. Anyone have any experience with the sound editor specifically and why none of the sound items would have nodes visible for me? Thanks in advance for any/all help. Cheers!
