I use the Google Calendar add-on to see my tasks in GCal, and the functionality is great!

For the last few days, the little task icons have been duplicated. I have two checkboxes for each day, showing the same tasks when I click on them. They also show on my Google Desktop sidebar calendar as two separate Tasks-lists.

I've tried unsubscribing and re-subscribing to the feed, but they are still doubled. I also tried the manual, cut and paste method for searching public calendars.

This doesn't seem to affect the function of the task icons in any way, but is more a cosmetic irritation.

Any thoughts on what I could try to fix this? Thanks.
