Since upgrading when I click the lock to unlock it, it immediately locks again in less than a second. Authentication succeeds. There is a password on my admin account. I have tried using both a local admin and a domain admin(which has local admin rights) on two different macs both upgraded from 10.13.6 to 10.14.0 with the same results on each. On one I have removed all MDM profiles, all config files under /Library/Preferences, and all config files under /Library/Managed Preferences, and rebooted, unloaded all plists under /Library/Launch/, and still had the same result. Other systems preferences areas will unlock without issue.
Has anyone else seen this? The only instances I can find of this on the internet are of people who don't have an admin password set.
