In some cases our WebCal Importer tool is duplicating a team's existing events, which is rather frustrating and something we are working on fixing as quickly as possible.
If you are finding this is the case for your team, please follow these steps to prevent your schedule from being duplicated.
1. Remove your WebCal URL from your team's Configure page.
2. If you know your schedule is being updated, use the Import Event >> WebCal option.
3. Check the events to be imported and add only the new or edited events before clicking the Import Events button.
You will also want to check your Event Page and remove your duplicated events. The quickest way to remove your duplicate events is to click the red 'delete' button for each event.
If you find you are still having difficulty with any of this, please let us know at email@example.com and we will do our best to get back as quickly as possible.
