Lights Showing Up On 'Unassigned'

I’m having a problem with lights appearing on multiple LightSelect elements. The problem is pretty straight forward. I assign a set of lights to one LightSelect element, but they also appear on my Unassigned LightSelect element. Is there a simple solution to fix this?

I’m experiencing the exact issue as discussed here: https://forum.corona-renderer.com/ Lightmix bug - Light jumps to enviroment when uncheck "occlude other lights"

Edit: I figured out if I uncheck “Occlude other lights” under Visibility it fixes this behavior.
