I have many situations with many persons with identical given names.
It would be helpfull, to display the field birth (year) in the list on the left.
many thank for realisation
The request for that preview has been reported to development. You can turn on the record numbers under Settings, General Settings, Number to Display to tell them apart. Otherwise, highlight the person to see their details on the right.
Close RM and reopen and see if the RIN is still showing as selected in Settings.
