Problem with setting the PIn on the map (OSM)

Hello

I have a confusing issue: When i started with the project i entered my (german) ZIP Code – and the result was an area and not the city only (because of small city). So all results where “City Area” and not “City”. I dont mind and worked on on the project but know i have realized that there is a problem if i wanted the relocate the pin on the map … Everytime i touch the pin i get the error “Please choose any address of the (City Area) city only.” but of cause i already entered an address – in the city.

I tried to change the city in the “Default Location” settings (here i can find the entry “City Area”) – but if i change it to my city – no entries will be found on the map anymore 🙁

Any idea how can i fix this?

Best regards
Velli
