Record has been marked as duplicate and has been retired, but current record is NOT same
I looked records attached as sources to Erik Eriksson M8P5-CMG and noticed that his birth record has been marked ans duplicate and retired. Then I viewed the current record. But that record is NOT a duplicate record. Child's name, christening date and father's name is same, but birth date, place and mother's name are different!
How it is possible that these two obviously different records have been marked as duplicate and then other has been retired??
How many other records have experienced the same fate?
