When you are adding a new user on the User Rights page, you must select the person’s username when it populates as you type it into the +Add with custom rights or Assign to role text boxes. In the example below, the user must click on the site_admin (REDCap Admin) auto fill or type out everything inlcuding (REDCap Admin)
If you type a name and hit enter without clicking on the username, you will still be able to add the name you typed but it will not be a user. It will be just text that is not attached to a user. For example, I can add “Fake User” to a project:
Notice how the user list does not have a name for this person:
Make sure the user you added has a username and name in parenthesis after they are added.
