Removing Device Names in Alexa App

I had some trouble with my Sonos setup a couple of days ago that required some troubleshooting. I have two sonos ones acting as surrounds to my playbar and sub in the living room. When I was troubleshooting I removed the surrounds and tested them as individual speakers and also as a stereo pair. When doing this, I had to give a name to the stereo pair and the two individual speakers. At some point, I also changed the name of the Living Room to TV Room thinking the issue may have been caused by a naming conflict. After my issue was resolved, I added the surrounds back to my living room setup where they will remain. Now, in the alexa app the names for my stereo pair and individual speakers still remain even though they are not in use. I now have 4 device names on the alexa app that are not in use. I understand that I will have my group name which is now Living Room and my two Sonos devices which are now labeled Sonos One Left and Sonos One Right. However, I also have devices named TV Room, Living Room Right, Living Room Left, and Stereo Pair. Again, I created these names when I removed the surrounds from my playbar and this was only done for testing purposes. I just need to figure out how to get rid of these old and unused device names. I have tried removing these in the "Manage Content and Devices" section in my Amazon account, but they do not show up.
