MapPress uses Google’s geocoding database, which only accepts street addresses. Google Maps (and embedded Google Maps) also search a separate database called ‘places’ for business listings.
In the places database, the address is entered by the business owner and may not be a valid street addresses (or at least not valid to Google).
I tried the address you provided and it is invalid per Google’s geocoder.
What address did you enter manually to fix it?
I don’t know if there’s an easy workaround for this. Hopefully it doesn’t occur too often in your data. Otherwise, I can look into having MapPress call the places database – but that may not be ready in time for your project and would be subject to various usage restrictions from Google:
