In Switzerland, ATC and other pilots, strongly prefer to only ever use names of places that are listed on the official ICAO chart.

Use official VRPs and proper aviation designated points when reporting your position. You'll find that no two charts are alike in their choice of basemap, and since towns and cities are not aeronautical data, consistency between two charts is not possible in this aspect, especially when vector charts like SkyDemon are infinitely zoomable so places will appear and disappear depending on zoom level.
