Hi,

Please reference steps mentioned in article “Reinstall the CA role in Windows Server 2012 Essentials” to un-install CA, then, re-start system and confirm that if you can demote AD DS:

Demoting Domain Controllers and Domains:

If problem persists, please open PowerShell and type command “get-windowsfeature” to list all installed server roles and features, and make sure that CA relate roles and features are successfully un-installed.
