Paul, I had the same problem at first, until I realized that there were multiple "pages" in the list of names on the left side, and the pins on the map correspond to the "page" of names showing at that moment. Scroll down to the bottom of that list to find the link to advance to the next page(s) until you find your name in the list - and you should see your pin. Hope that helps.
