I don’t know that plugin, but in general you must pay attention to any third party plugin that works with JS as they could be in conflict with the API we use.
We can not fix any third party.
We can review and estimate building a feature in the theme as custom work. I don’t know how radius must work. So please open a ticket here if you wish custom work http://support.wpestate.org/ and send all the details for my partners to estimate and get back to you.
Please note custom work requests that a few days to be answered as we are very busy.
