Use Profile Section cleanup to manage profile sections.
The Profile Sections page provides you a one-stop interface to view and edit different sections of profiles created by you. Click on a section link, for example, Hobbies, in the Profile Sections table to access the multiple fields associated with a profile section. You can delete the unwanted fields using the delete icon. You can also view the section fields by clicking on the view icon of the section given under the Options head.
