I deactivated all plugins except “The Events Calendar” and “The Events Calendar PRO” (the item in question is an Event page, not a page or post), and I’m still getting the same results. When I update a page or post, those options operate as expected. This appears to be an conflict between the plugin and the theme. This is a major, highly used plugin, could you look into the possible conflict and for a resolution? Thanks for your time in investigating this!
