I'm getting duplicate events in my iCal feed using the velocity format for an iCal output that came from the Hannon Hill Calendar Site import. I think it is left as it came from git, but just in case I changed anything, here it is.

Here is a link to the .ics file: www.bcgov.net/calendar.ics

Anyone ever run into this problem before? Thank you.
