Attention Curators Please Assist

I inadvertently did an incorrect merge moments ago (my fingers slipped), resulting in Peter Schmidt at Peter Schmidt having 2 sets of parents. I can’t seem to remove the incorrect parents.

Could someone assist please? It would be very much appreciated .

The correct parents are Jacob Schmidt and Lencke Nachtigahl.
The incorrect parents are Jacob J Schmidt and unknown.

Thanks in advance. My apologies for creating the issue.
