As your profile details are private they can't be seen. Try this:
Go to your profile, across the top - click the EDIT tab. On your page, scroll down the right side and look at the 'children'.
If you are listed as your own child, first click on that child and make sure the WikiTree ID is the same as yours, and is not an accidental double entry with a slightly different ID.
If it is the same person - go back to your own profile,
click the add/edit link below your name as child.
On the page that comes up - scroll to the very bottom - and click the button that allows you to remove that child from yourself as parent.
If you that doesn't help, you could add me, or one of the other responders to your trusted list so they can help fix it for you. Chris
