Can you troubleshoot?
name of the task is "Add yelp friend :-) "
Please try to log out on the web, clear your browser's cache, reload it and log back in and see if the duplicated task still exists.
If it does - can you remember in what situation did you add this task exactly? In offline mode? With an unstable internet connection? Any detail would be very helpful.
I tried that but the issue insisted.
Not sure what exactly happened ... after a while I got the duplicate on the iPhone as well (while syncing :-( )
Anyway, consider this resolved for now, if it happens again I will let you know.
