Map Unavailable

Hello there, I’m in development stage of setting up the website where people will need to RSVP for any of the events. I’m using the Event Tickets in conjunction with the Event Calendar plugin. When I set up an event using Tickets plugin, I noticed that the location isn’t displaying the map and it said “Map Unavailable”. When editing the Location page, it said “Location Not Found” under Where section. Am I missing something here? Do I need to install Google Maps or how can this be resolved? Thank you.
