What result did you expect?
When the result in the right place and just named wrongly:
15, Ersintie, 2, Kauniainen, Helsinki sub-region, Uusimaa, Mainland Finland, 02700, Finland
Further details
Address is inside Kauniainen municipality, so it shouldn't contain Ymmersta or its parent Vanha-Espoo. Those are in Espoo, which is another municipality altogether.
In fact the point is not even enclosed by those relations, so it is unclear why they are returned. The same query with zoom level 14 returns the correct neighborhood.
