Multiple Entries on a single address

Just came across two instances of another issue: multiple entries at a single address...no way to view the "bottom" one on the map (so unless you know to do a search for it, you can't see the first entry)
Again, let me know if you want further explanations. For an example, zoom into the Millennium / Olympic Village, you'll see it says 2 entries, but when you get in close, there's only one green marker to click on
