Complementary spouses have a complementary spouse statement, although with qualifiers and jazz. What's going on here? doesMade a statement to find spouses that do not have a complementary spouse statement. It works for the most part, but I'm puzzled why it lists spouses that PS. I already added the missing spouse statements, meaning this query is supposed to return no items now.
