In OSM it is mapped as within Clifton Park, not in the Halfmoon. Note purple line in https://www.openstreetmap.org/note/1020593#map=16/42.8788/-73.7716&layers=N and its labels.

> When populating from this map on various websites, it is showing as Halfmoon. 

This is problem in some other dataset or in ignoring mapped admin boundaries in OSM.
