Issue Summary

When you have a calendar that only has one custom event type, and you embed the calendar on a Confluence page - clicking on "Add Event" on the page will prompt you to select the event type first before displaying the full "create event" form."

Steps to Reproduce

1. Create a new Calendar
2. Add one custom event on the calendar
3. On the "Manage event types" form, deselect all event types except the newly created custom event on #2
4. Go to a Confluence page and embed the newly created calendar
5. Publish the page
6. On the embedded calendar, Click on "Add Event"

Actual Results

The "Create Event" form will not be populated with all fields. It will prompt a user to select the Event type, although there is only one event type.

Expected Results

The "Create Event" form should populate all fields with the custom event type selected

Workaround

1. Click on the dropdown arrow on "Event Type"
2. Select the custom event type again
