Number of Manhattan lead variants does not match numAssocLoci from API

I have found several studies where the number of variants returned from “search” in the API. For instance, when I search for GCST003602 via the API, numAssocLoci is 6. But study summary page and manhattan only has 5 variants. It seems like the numbers generally differ by 1 (though not always). Here are some other examples. I’ve listed the number of hits from search or manhattan:
