Unable to geocode for some points

[dhananjay-via]

I setup my own nominatim server 4.0 version using docker, with the region Wisconsin downloaded from the geofabric with importstyle=extratags
and when i try to call reverse with a point, it is unable to geocode for some points and also state doesnt comes up in address for many points

below point is from Wisconsin state
example: http://localhost:8080/reverse?lat=42.56311&lon=-87.91859&format=jsonv2&zoom=18&extratags=1
fails with "Unable to geocode"

but getting result for this: https://nominatim.openstreetmap.org/reverse?lat=42.56311&lon=-87.91859&format=jsonv2&zoom=18&extratags=1

am i missing anything during import or any?
