map marker are not displayed after search

Hello, congratulations on this great plugin.
I have an issue with search feature.
Althouph the results are displayed properly, the map markers are not visible at all!
I’ve checked web console and i see the following js errors:
– InvalidValueError: setPosition: not a LatLng or LatLngLiteral: in property lat: not a number
– InvalidValueError: setMap: not an instance of Map; and not an instance of StreetViewPanorama

I added google api keys and all the required fields in plugin settings.
I use jupiter theme from themeforest.
Does anyone have the same issue?
George.
