I'm not sure what you are calling the realtionship button.
The line above her box where the parents' first names are given and she is the selected person is showing the wrong parents. If I am on the previous page where she is listed as a child, the parents are correct but I cannot get there by going back from her page. I have to pick her father from the index of individuals.
I have no idea how or when this happened, I was doing some prep work for a trip and just found it last week.
I am using Windows XP and FTM 2010.
