I have a C425 and a C120. They are both linked to my Alexa devices. When a person is detected, announcements are stated TWICE! 

I had this problem before and somehow was able to eliminate one of the announcments, but I don't remember what I did to make it drop one of the two. (Wish I'd made notes.)

I recently figured out how to stop my bedroom Alexa from making announcements at all by setting it to Do Not Disturb. I did this because I didn't want to be woken up early in the morning by people coming and going. Anyway, since then, my other two Alexa devices have somehow reverted back to announcing person detection twice. Does anyone know how I can fix it again?
