Howdy James–nice to see you again!
I see what you mean. Based on the options you have checked in the User Role Editor plugin, everything that is showing in the Events menu should be there. If you wanted to remove Venues and Organizers, then you would uncheck those capabilities as well.
I can see how the Event Add-Ons option could get in the way though. Unfortunately, that one’s not tied to a specific user role. However, we do have a tutorial on how to remove it across the board.
Let me know if you have any additional follow-up questions. 🙂
Cheers!
Geoff
