Publishing to Apple Calendar

When I publish Omnifocus tasks to Apple Calendar, in the Forecast view those entries are duplicated under “Calendar Events.” Also, in the Calendar Application, if I check the Omnifocus Calendar under subscribed calendars, the events appear twice in the Calendar Application. If I uncheck the subscribed calendar, the duplicates go away, and I am still able to see any new tasks entered in Omnifocus. These are repeating events, if that makes a difference.

Any insight?
