Hey Kelly,
I’m sorry to hear that only one event is showing. While listing all events on the map is not possible by default, there should be many more than just one! 🙂
To help investigate why that’s not working, can you share a link to your site where this is happening?
Next, can you post your site’s system information here? I will use this information to investigate why only one event is showing up. Here’s how to share system information → https://theeventscalendar.com/knowledgebase/sharing-sys-info/
Cheers!
George
