When trying to delete a never-used, duplicate leader account, I receive this message:
Scouts who are activated with advancement sync cannot be deleted. Should you need assistance you may contact your local council. If you do not know your council’s contact information, you may find it by going to Scouting.org, select Join from the banner at the top of the page, and enter your ZIP Code. The council information will display at the top right corner of the screen.
Obviously this is not a scout.
