This doesn't look very unusual. The only thing I could think off is
that you might accidentaly be using the wrong database due to the
fact how the import works. But I'm sure you have checked that.

These are the wrong wikipedia files for a 3.5+ version. See
https://nominatim.org/release-docs/latest/admin/Import/#wikipediawikidata-rankings

But that's just a note on the side. The wikipedia rankings have no
influence whatsoever on the formation of the address.

I honestly don't have any further ideas where your villages might
have gotten lost.
