Leviton DW6HD dimmer entity does not appear in all expected places

I can see my dimmer on the home page and I can control it.
I can see the entity that is turned on and of in the logs
I can see the entity in developer tools/states

I can manually create a scene in the scenes.yaml file and the entity responds.

However, the entity is not listed in devices or entities in configuration. When trying to edit the scene I created, it is not listed as a device in that scene.

Also odd, when I click on edit for the scene, the scene executes, which could potentially be problematic if the scene were controlling something more critical than a light, like some sort of pump or other mechanical equipment. I would think edit would only edit and not run a scene.

If I turn on advanced mode, it appears in the scene editor as an entity without a device.
It also appears in the configuration/customization menu.

I guess I’m confused as to why a light switch would appear as an entity without a device, and why advanced mode would have to be enabled in order to see it, and the fact that though it is a functioning entity with an id, it does not appear in the entities list.
