Maps not showing correct location on events

We are using Events + and are having an interesting issue with map display. When we are setting up events, we enter any name in the "Venue" field and the address in the address field. The map, while still editing, shows the correct location. When the event is published, the map shown has a location that is totally off, like in a different country. When you go back to edit the event, the location on the map is correct, but is again off when it is republished. If you put the address in the "Venue" field, the map shows up correctly when the event is published. A couple of questions -
Any idea how to fix this?
Is it possible to display the address on the published event rather than just the venue name?
Are these just settings that I am missing?
