Hi Robert. Sorry you’re experiencing this.
When you refer to “your main events page”, are you referring to yoursite.com/events/ or somewhere else (e.g. a custom page with an embedded widget or shortcode)?

General troubleshooting tips:
First, make sure you’re on the latest version of WordPress core, all plugins, and all themes.
Please follow our Testing for Conflicts Guide and see if that helps narrow down the cause of this.
If it doesn’t, please share your System Information. That will give me a lot of extra information to help diagnose the problem.
Let us know what you find out.
Thanks.
