Howdy Christine,
Thanks for taking the time to reach out to us. What you’ve described sounds like a conflict between your theme and The Events Calendar. Probably easily resolvable by writing a tiny bit of CSS and inserting it into your theme.
Have you purchased a license from us? If so, would you mind logging in so I can verify your support access and then sharing a URL to your website so I can investigate the issue further?
Or, if you don’t want a license (which includes a year of support) you should checkout the volunteer community onĀ WordPress.org: The Events Calendar. It’s not the same level of support, but it’s free! We even check those forums once each week so you should be able to get help at some point. Just make sure to share a link to your site, because likely no one else will be seeing that line and thus can’t inspect it/find out how to fix it.
Does that all make sense? Will that work for you? Please let me know.
Cheers!
– Brook
