I have somehow attached a blank "Child" record to a family and I cannot delete or unlink it from my database. It actually shows Sex as "M". When I double click it, nothing happens, either in Family view or Descendants view. When I select it and try to unlink or delete it, I get a message that I need to select a person on which to perform that action. When I highlight it and select "Pedigree," a blank pedigree chart appears saying, "+ Click to add a person".
In addition, the following person, along with an apparent Record #, appears in my Index of persons: [UNKNOWN], [Unknown]-180628128. I'm not sure whether this record is the same as the one described above, but it displays a nearly blank line that identifies its Sex as "M".
How do I get rid of this "person"?
Addendum: I went back and Restored my database from several Backups. I found that the last 4 or 5 Backups include the [UNKNOWN], [Unknown]-180628128 person. The most recent one that did not include it was my backup from 10 Oct 2017.
