Display Name & Birth Surname Issue

Having just gotten rid of the (No name) problem in non-US English versions of Geni, I discovered a new problem today, which behaves just as erratically but where it doesn't help to change from my language (Swedish) back to US English. In a lot of profiles (but not all) of married women, the Display Name has changed to add their Birth surname after their married name. This shows up in the Profile view and, like the (No name) problem also in the List view and in other views generated by Geni, while it still displays correctly in the tree view. I have set the Name Preferences to "Birth surname appended, in parentheses (tree only)" and removed the check mark from the "Ignore display name" box. So far it has worked very well, displaying correctly in all views. No longer. Here's an example: http://www.geni.com/people/Hanna-Dahlqvist/5319753689510089436. There are other examples in her profile view of Immediate Family, where her mother and married sisters have received the same treatment. Since discovering this problem, I have tried changing the Display Name manually, and that appears to work, but it feels like an almost hopeless task to do that for all the affected persons. Is there a hope for a general solution? What spooks me the most is that the profile's Display Name has actually been changed...
