Chris, Google's agreement doesn't allow you to use lat or lon for any other purposes than showing them in a Google map, and because of that we do not encourage the usage of them.
Thanks for reporting this Christopher. This issue has been fixed and published to the Liferay Marketplace in version 1.0.1.
We also have a dedicated Jira project for all of our Liferay Apps (http://issues.rivetlogic.com/browse/LRA). Please feel free to use it moving forward for bug reports and enhancement requests.
