Task updated not working correctly

When I edit a previously created task and then close it, the updated task appears correctly. However, when I reload the site to make sure the edit got uploaded to the cloud, that task reverts to the prior version (deleting the edit I made). I noticed that I can ensure that the edit does stick by moving the newly edited task to another spot on that day's list of tasks. http://whatsmybrowser.org/b/1QQCFCY
