I have created a new user and copied permission from an existing user.
The new user is now created twice
- The new user name is now linked to the existing user email address with the new user first name
- The new user name is linked to his own email address with the new user first name
The existing user: Try to change the first name and surname to the correct name, but it does not work.
How can I update the name as mentioned in point 1
