Help w Google Map API Limit

I have a plugin that places listings on a google map. It requires an API which I installed. According to Googles API console, I have had only 13 requests in the last 24 hours. However in the plugin, it is saying I have reached my daily limit which, according to Google, is 25000.

The plugin developer said that because I'm on a shared server that other websites could be maxing out my limits?? How is this possible when I have a dedicated IP? It should not matter where my site is hosted. The API limit is per IP, isn't it? Nothing here about shared hosting.
