I just upgraded from Lion to Mountain Lion. In the Reminders app, I noticed that there is a new list simply called "Untitled" (which appears in the "On my Mac" category and not the "iCloud" category). Is this new list a part of Reminders? I would like to delete it, as I have no use for it, but I am unable to do so. I have also noticed that this list is only found in Reminders on my MacBook Pro and not on my iPhone or my iPad. Thanks.
