Googlemaps in Editor and Live Modus

Hi guys I am new to Wix and am currently at a problem in despair.
I have a dropdown menu, database and googlemaps on my site. Based on the selection in the dropdown menu googlemaps should take the new address from the database and display it.

In preview mode it works fine but in live mode only the address of the first entry is displayed, no matter what you select.
I looked at the debug mode and see that the first time it says:
[Dataset - Connected] ‘XYZ’ collection to element ‘#googleMaps1’:
but then no further entry, with other elements connected to the database happens the following:
[Dataset - Connected] ‘XYZ’ collection to element ‘#table1’:
and then again and again:
[Dataset - Populated] ‘XYZ’ collection into element ‘#table1’:

Can someone please help me and explain what I am doing wrong?
