When trying to add roles to a user , Add to List does not bring up a list of roles.
As a super User
1- Navigate to User
2- Under "Roles Assigned To" select "Add to List"
Nothing appears in the list
As a workaround you can assign the user to the role instead of assigning the role to the user
1- Navigate to the role
2- Under "Assigned User" select "Add to List
