There is currently a limitation with syncing Google calendar reoccurring events. If you delete an instance of the reoccurring event in Google, it will still appear in 17hats. This is because we can only retrieve the original event, and then we show all the subsequent events. Google does not tell us if a specific instance has been deleted. So when you delete an instance of a reoccurring event in your Google calendar. You will also need to delete that instance in your synced 17hats calendar.
