I did find it using the method you suggested and I changed the sections in Applicability\Branch and UI\Selection from Dev to Beta, then rebooted. They reverted back to Dev?!
Perhaps it's time to delete the entire WindowsSelfHost key and rejoin as you mentioned in your original response?! Are CU updates the same as Beta?
Thoughts?
If after that it reboots with me joined to the Insider Program and filled in both places as dev -
it's Demon Computer Be Gone time ;)
