I have two strange issues (i dont't know, they have the same reason?):

1)
When i enter the hotspots-dialog (for e.g. entering a new or modifying a hotspot,) the message "[Starting Position] undefined“ -> see screenshot

2)
Geocode does not work (see screenshot). If i enter an adress in a hotspot-item and geocode it, the error appears (Entschuldigung, es ist uns nicht gelungen, Koordinaten für den angegebenen Hotspot zu finden).

What can i do?
(Yes, Google Geocoding API is active)

Thank you & best regards-Thomas
