Android map overlay issue

I have a set of points(5-10) that needs to be overlayed on the map. I am able to perform the overlay function correctly, the markers corresponding to the points are displayed on the map. But android skips adding the first two points for some reason. Any clue why that happens?

All these are the points are added to the overlaym after which the populate() method is called.

Yann Martel, Paul Thek, and Ordinary Madness all have the same exact Coordinates. So all points are there, just on top of each other.
