Maximo comes with the supervisor displaying the name, out of the box. The relationship looks correct, so you should only need to load the supervisor field on the person record, and when you display it in the people application, the corresponding name for that person should display.
Check the data you loaded and ensure it matches the present person data. You can always find a record that appears to have an error, select that person from the select value, and then save. If it works, you had a data error on the load, which I am guessing is the issue.
