How do I fix icloud profile?

Here is my problem. On icloud website. My profile is attached to a random contact on my contact list. How do I fix it so that is it only attached to a specific contact?

For example: Let say my profile name is John Smith. My icloud's profile (picture) is attached to John Doe's contact info (it has a human symbol attached). I do have my info as a contact. How do I change it so that my icloud profile (picture) is attached to my contact.
