I have the menus setup a little odd right now to make it harder to get to the All Calendars view. Go to events and select All Calendars, then go to April 2024. https://outsidepolice.com/events/2024/4/
Mecum Auto Auction on April 4th 2024 is on the Schedulers Calendar. It should only be visible to members of the Website Administrator's group.
After clearing all the caches that I am aware of, I logged as Sal Sanchez and still see Mecum when viewing the monthly calendar under All Calendars. It is correctly filtering out the Supervisors, Schedulers, and Group A Calendar in the drop down.
