custom fields for google maps plugin not working

I am using the google maps plugin on the Spirit theme. I populate a custom post type with long/lat coordinates but have been unsuccessful in getting google maps to generate a map based on those custom fields and coordinates, the documentation doesn't show how to place a map into spirit theme that will use the custom fields as the data points.

I also tried doing it another way using the following shortcode -
[location coordinates="-37.84119,144.94071"]

replacing the hard coded lat/long for the names of my custom post fields, that didnt work either. Is this google maps plugin working properly or is there a bug?
