Hi Pat.
I see you have the same name for a Venue and an Organizer. Is that correct?
Also, what post type is the “raised at a Frock Swap” post?
Please follow our recommended troubleshooting steps:
Could you please make sure all your Modern Tribe plugins (and WordPress core) are at their latest versions?
Once you verify you’re on the latest versions, please test to see if the issue is still happening for you.
If it is, 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.
