Hey @Olivia,
Thanks for reaching out. I find the same thing when Event Tickets and Event Tickets Plus are activated.
This is partially by design, and partially a bug/design improvement we need to make.
I have reached out to our developers about this; perhaps we should change it from “Events” to “Tickets”, and change the sub-menu “Events” to “Settings”.
However, if you are looking for other menu items like Venues, Organizers, and so on, these are only available if you also install The Events Calendar.
I will post updates regarding changes to the menu structure as soon as I learn more about our plans to improve this.
Thank you!
George
