Scene builder shows two entities

I have been using HA for a few years and always used YAML. For various reasons, I am trying the GUI method.

In building a scene, I choose the device and two entities pop up.

Does this affect anything? They do not always track each other - one can be on, the other off, though this is one physical light.

I believe the “Basic” entity was added to meet certification requirements, in my experience they aren’t needed. I turn them all off in the entity settings. YMMV.
