Nominatim merges two map features when they represent the same (relation https://www.openstreetmap.org/relation/179194 and node https://www.openstreetmap.org/node/66503091). The node is tagged as place=village. Try reviewing and changing that.

Degraded Tonzolano to hamlet (which is in fact part of Buja) in OSM so that Buja will be the only village in its administrative boundaries
