One of the people in my tree has an issue with the parents. Multiple entries are present on Family Search, and it appears that the father and mother were imported from separate entries.
First I would ignore the FamilySearch entries for now and put together the family in your RM database. You did not say whether you had children for any of these parents listed on left hand side. I am assuming you likely have some children.
First backup your database. Then write down the record numbers for the each incidence of the parents and the children. Next you will need to unlink all the children from instances of the parents and any combinations linking parents together.
Once your people are alone (unlinked) in the database, link the father and mother together one time. Then link the children to this couple.
If you want information from any of those FamilySearch entries, I would type it in by hand without trying to merge anything automatically. Auto-merging the mess in FamilySearch with your corrected database will just cause problems.
