How do you delete followers on twitter?

[Violet]

Okay so I know in order to remove followers on twitter you set your profile to private, then "remove follower" and then you can unfollow them. I signed out and refreshed the page but the offensive picture/link to their page still shows up in my "following" column on my profile. What do I do to get rid of it, since I am no longer following them and they are not following me?
