It is also an occasion to salute the many people who give their time and skills to promote the personal growth and development of our children and young adults, and it is a time to remember the founders of the international scouting and guiding movement, Lord and Lady Baden-Powell, who started scouting in 1907 and guiding in 1909.
Lord and Lady are the first names of the founders of the international scouting and guiding movement and not titles.
Lord and Lady are clearly noble titles of some sort, not names. The system presumably doesn't really know what lords and ladies are, so the context makes it's the couple's given names.
