2 Identical Installs Different Behaviour

Two installs with the same exact configuration.
Theme, Genesis 1280
URL1: http://bizzaquerque.com
URL2: http://themindproject.net

For URL1 go to home page and click on any listing on the home page. It will return the details page with the GD Map at the top displaying only the location of the listing clicked on. I love this functionality.

For URL2 go to the home page and click on any listing on the home page. It will return the details page with the GD Map at the top displaying all locations.

I have compared each site’s configuration twice and there isn’t anything I can see that explains the different results.

I would really love to have URL2 behave exactly as URL1.

Any help is appreciated

Thanks
Dan
