If you want to confirm a place and get the message "No coordinates were found for this location", no location could be identified on the map that matches the name you entered. You can now manually choose any location on the map.
To do so, follow these steps:

• Locate the right spot on the map (use the navigation elements and the zoom slider).
• When you found the right location just click on it in the map.
• Now simply click "OK" and the marker will be set on the spot you chose.
