Hi there, @Patrick_Carroll 
I’ve checked your website and the console is reporting that Billing was not enabled while setting up the API key. This is the reason why your Map is not loading correctly:
Please follow this link from your console and enable Billing there - https://console.cloud.google.com/project/_/billing/enable.
You can also find the details about enabling the billing in this article - How to get Google API Key for Google Maps widget.
Let me know if it helps and if any other assistance is needed
