Hello and welcome back!
First off, thank you for running through our Testing for conflicts guide 🙂
I did a bit of testing and also took a look at our logged bug reports and can confirm you’re experiencing a known bug. For right now, you can revert back to versions 4.1.3 and you’ll notice the settings reappear.
You can download older versions of the free plugin here: https://wordpress.org/plugins/the-events-calendar/developers/
You can download older versions of the PRO plugin here: https://theeventscalendar.com/my-account/downloads/
And follow these steps to manually update the plugin: https://theeventscalendar.com/knowledgebase/manual-updates/
I’ve attached this thread to the logged bug report for the developers to reference. Please stay tuned to your wp-admin and theeventscalendar.com/blog for maintenance release info. Thanks again for providing thorough information in your initial post and have a great upcoming weekend.
Cheers!
