The Events Calendar hcalendar

I have recently installed The Events Calendar plugin. When i add events and run the event through googles structured data testing tool I get 2 errors and 3 warnings on “hcalendar”.

The errors are dtstart and location and the warnings are description, dtend and URL.

The “event” only comes up with 1 error which is performer, the other fields are all complete.

I have completed all of the relevant fields when adding the event and can not understand why hcalendar is not pulling through the information.

Any help would be much appreciated.
