Hey Matt,
Thank you for reaching out to us!
I’ve created a couple of venues in my local install but wasn’t able to reproduce the issue you are experiencing.
To get started, please make sure that all of your plugins are up-to-date. If the issue persists after updating the plugins, I would also recommend you to run a Conflicts Test. You can start the test by temporarily deactivating all of your plugins (except Modern Tribe plugins) and changing your theme to another one like Twenty Seventeen and let us know if the problem is solved after that (don’t forget to backup your database before changing anything).
Please run the test and let me know the results. If you have any other questions in the meantime, please feel free to let me know and I’d be happy to help as best I can!
Cheers,
Patricia
