If the name is not misspelled navigate to:

- From here you can see what Roles the User has. If they have Past Student and Student (2 of a User Role such as Candidate, Past Candidate, Student, Past Student) then this is why they are being displayed twice.
Let Support know and we will be able to remove the incorrect Role.
