In the People Workspace, Family View, with Scottie as the "husband" or in the Left Box (where the parents are listed). Look at his wife. There is a Spouse ICON. What is the number next to that ICON? I am guessing it will be 2.
That would indicate 2 spouses, one of which is the Unknown Spouse. Detach that Unknown spouse of Scotties spouse. (People, Attach/Detach, Detach spouse).
