Hi John,
Thanks for reaching out! I’m sorry you’re running into this issue, but I’ll be happy to help you figure it out!
I tested this out on my end but was not able to recreate the issue. Is this happening with all recurring events or only certain ones? If it’s only some of them, can you check to see if they have anything in common (such as being featured events, etc.)?
First, I would recommend upgrading to the most current versions (I don’t think this will resolve this particular issue, but it’s a good place to start!). The Events Calendar is at 4.6.1 and Events Calendar Pro is at 4.4.18. If you don’t see a prompt to update in the Plugins section of your WordPress Dashboard, you can do so manually by following these instructions.
Next, can you try testing for conflicts with your theme and other plugins? If you would prefer not to do this on your live site, WP Staging will let you create a quick copy of your live site that you can use for testing. I would pay special attention to Yoast when testing, as the settings there can sometimes result in odd behavior related to links.
Let me know what you find!
Thanks,
Jennifer
