Merging whole families.
In the past it used to work!!
A married couple has 8 children who were duplicated with the same mother.
All the ID numbers are exactly the same.
Instead of having to delete the duplicated, children individually from the mother, we were able to do it in one step and that is just ADD the father's ID number to his spouse and, they are all immediately corrected.
Please try using this family Coenraad Hendrik Fick LZ8C-HW1 and his wife LH9Q-9HW.
It tells you that they are already linked. Surely this can be corrected again?
