Missing the option to change forms

Hi,

I’m using the Event Manager plugin for events that are being posted on this website. It’s working fine, but I want to add something new to the form. The problem is, I don’t have this option in my WordPress available for some reason. I was doing research and I stumbled across someone who had the following option:
– Events
– Add Event
– Locations
– Reccuring Events
– Bookings
– Settings
– Help
– Forms Editor
– Payment Gateways
– Coupons Manager

My option are a little more limited, it ends at help. So I don’t have the Forms Editor option available. Any ideas how to fix this?
