Getlocations problem - creating new map instead of updating existing one

Hi. Once again Entity reference autofill saves my project. And as last time i find something strange happening ;) It is not very critical problem but it will help me to go further with my site.
Here is my configuration:
Content type 1: Venue
Fields:
- Name (node title)
- Location (Getlocations module)

Content type 2: Event
Fields:
- Event name (node title)
- Place name (entity ref. with autofill. Reference to "Venue".)
- Location (Getlocations module from "Venue")

When I create a event for the first time it works very well. But when I edit existing Event node and choose different Place name (my Location fields re-fill with new location info) and click save I see two maps: one with old location and another with new one.

I also tried to edit node and manually change Location without touching Place name field. After save it works fine. I see one map with updated location.
