Alexa - Kitchen Doesn't Support That

No, I just set it up.

The switch does not share any name. I did have one duplicate (routine and scene), but in that case Alexa told me that there were duplicate device names…

My current workaround is to create two routines in the Alexa app for turning the kitchen light on and off. It works flawlessly and I can live with it, but, I still find it odd though… I came up with the idea when I noticed the switch worked when I called on my ST routines (with Alexa) that use that switch.
