Issue Summary

If a calendar has multiple custom event types, the ICS import does not import custom event types and Events under the custom events are converted to the default event.

Steps to Reproduce

1. Create a calendar on Team Calendars
2. Create two event types (Custom)
3. Add events for both event types
4. export the calendar to an iCalendar (ics)
5. Import the calendar on any calendar client or to a different space

Expected Results

All events and event types should be exported

Actual Results

The events are exported but the event types are converted to the default event.

Workaround

Currently, there is no known workaround for this behaviour.
