Hi Maureen. If I am seeing this correctly, there appears to be just one Renninger-239 who was inadvertently set as his own father (and therefore both the father and brother of Adaline). If Frederick is actually the father, and Adaline has no brother, then I think you should be able to fix it by going to the Edit screen of Frederick's profile, in the Edit Family section on the right side, and just removing him as a child. (Click the Add/Remove link, follow the instructions, and Save.)
If that doesn't work, or I misread something, please post another comment here.
