[list_organizers] displays venues
Can you uninstall and reinstall the plugin at https://theeventscalendar.com/knowledgebase/listing-venues-and-organizers/? I tested and was unable to reproduce your results.
Please let me know if that resolves the issue.
I checked in to this further with our extensions developers. It seems this is a bug. We have it on file and you will be notified when a solution is available.
Because this is not a primary plugin, it is worth sharing this reminder:
Please note: we hope this plugin is helpful and useful for your site. That said, use this plugin at your own risk. If the plugin causes problems, simply deactivate it. We are not able to provide support for conflicts or errors caused by our helper plugins. If you need help installing or activating the plugin, please review this WordPress Codex article http://codex.wordpress.org/Managing_Plugins#Installing_Plugins.
