Events App

Hi,

I've used the Events app on a site. Obviously within the system I have created myself as the primary admin and then the rest of the users are editors (I don't want them open to all of the features). Within the roles section, I have checked the all of the boxes to do with events (access events and manage categories) however the editor accounts are not showing the button to add a new event but the primary admin is. Is there a check box I'm missing?

Thanks!
