@Fellfrosch, Pappenheim was sorted so down in the list due to the preference to the objects which have less levels in their full name. When looking at search strings, you could see the number of levels through the number of commas in the string. Obviously, this doesn't work that well.

The issue with too long strings in Pure Maps navigation overview is resolved now and will be available with the next release
