I'm trying to add to the biography of [[Marsh-1378|William Marsh (1673-1744)]]. I want to add a copy of an entry from his daughter's biography, Deborah (Marsh) Harlan. The entry is about his will. When I copy the entry from Deborah's biography (including source citing) into [[Marsh-1378|William Marsh (1673-1744)]]'s biography, the source doesn't show up in the preview. I've run into this before with other profiles that were created some time in the past. What am I doing wrong?
