Hello @EncinoMan, and welcome to Ten Forums. :)
When this happens, it's usually caused by having an incorrect password entered in netplwiz when having Windows set to automatically sign in to that account at startup.
As a test, check the Users must enter a user name and password to use this computer box in netplwiz and click/tap on OK to see if you still get the incorrect password with duplicate account afterwards.
