In the calendar view there are two different icons that show up next to events (in list view). Both look like the standard calendar icon but one has two semi-circle arrows (together to form a circle) on top of it. Does anyone know what the difference is? The events seem identical other than this. Trying to eliminate some duplicates and this is the only difference between the two entries. I couldn't find any information online so hopefully somebody can help me out on this one.
