Go to "Contacts." You can remove single contacts one at a time or select a few to be removed from the list simultaneously. Check it off and click "Remove contacts" to remove a contact. You will receive a notification saying, "The contact has been removed."To remove a few contacts or all contacts simultaneously, click "Select all." All the selected contacts will be checked off automatically. Click "emove contacts" to delete them from the list.
