@harm-arend Hello, this problem should be addressed to Open Street Map, since we use their maps and have no control over them. Once the map is corrected on OSM, it takes some time for the changes to be reflected in the application as well.
Please also note: For every language, a different place name label can be displayed, so please choose your correct language and data display.
Further discussion of place name and language issues or disputes should be directed to the OpenStreetMap Forum here: https://forum.openstreetmap.org/index.php > scroll down & select > users: (the relevant country for your dispute and/or question)
In the case of a political dispute please leave such topics out of the Windy forum and instead focus on the discussion of weather.
Changes made in Open Street Maps do not occur instantly in Windy and will instead be updated periodically in the future.
