@leighleigh: If you open the Calendar app, then tap on the date that the event is scheduled on, then it will bring up a pop up window, with all events for that day arranged in chronological order. Simply tap on the event in the list to open it, then tap 'Edit' at the bottom of the screen to make any changes. Once you've made your changes, hit Save. Let me know if this helps.
This is what ir looks like.. no cursor either..its just locked.
@leighleigh Did you import this calendar event from a third-party app? Or did you create the event in the Calendar app?
