GE Enbrighten Z Wave Switch Models

Could someone explain the differences in models, specifically the toggle. I have one model that has an LED built in, which is fatter, and another that does not have an LED built in, and is narrower. The narrower switch is detected as a generic switch, where the fatter one is detected properly as GE Enbrighten. This isn't the add on switch. The narrower switch does not have the vertical white plastic piece beside the toggle either.

can you post photos of each or the model number if you can see it?

Sorry for the delay. 4003 is narrower and doesn't light. 4009 is fatter and lights up blue
