OS Property Map Module - Red Icons Display Help?

Hi Jonathan,
What is that layout? The red icons are bound (combination of more than one marker) while the blue icon is one marker.
Thanks
Dam

This is a screen shot of the display of the OS Property Module. This is displaying on the home page of my website: I located the folder and changed the map icons to the blue ones displayed. However, I'm unable to locate where to change the red icons with numbers. Where are they coming from?



Why doesn't it display in the same style as the maps displayed in OS Property component. I'm using Yoo Theme Templates. If it not working correctly should I submit the back end log in info via a support ticket?

Thanks,

Jonathan
