I have enabled clusters. See screenshot… ( https://snag.gy/GtEPsM.jpg ) and I have 2 markers that are very close to eachother in the city of Miami, FL . I expect to see a cluster of 2.
Clusters displays number of locations, if your two locations are very close to each other then when you zoom out you will see spherical marker with number of location. Like if you have 15 locations in a city and when you zoom out then a single cluster marker will display 15 marker locations in a single marker cluster.
