When you click the locations the FIRST TIME, they push the info window off the top of the map. If you go to another one and come back to that or just click it again it centers properly in the map. How can I fix this? Is it a setting for the window itself?
It is something issue with marker cluster. Please disable marker cluster and check issue is resolved or not and let me know.
