Preferred relationship is stuck on wrong relationship
kwc2-gtb has two marriage relationships. One marriage is to kwc2-gty which is to my biological grandmother. The other relationship is to l8b7-z4p which is a step grandmother. I would like to have the marriage to kwc2-gty be the preferred marriage but is stuck on the other marriage and will not change even after following several steps tried with the assistance of a missionary at the SLC familysearch library.
