Joan, I have changed the gender to Female. I was able to do this because these profiles are public. Do you want your family profiles to be public? I don't know who added these profiles to Geni, clearly it was not you and the person did not know Terry's gender. Perhaps you should be added as manager on your close family profiles and if you want them to be private, you should request that. Often, people choose for all living family profiles to be private, only viewable by those who are in the Family Group.
We can tell you how to request to be added as a manager.
