Synced items missing from Sync menu
I've been trying to free up some space on my iPad by deleting synced episodes of shows/movies I've watched only to discover that a number of items I've synced are not showing in the SYNC menu. This means that the only way to remove them (as far as I can tell anyways) is to remove everything.
Does anyone have any idea as to how I can fix the problem? Why I can't simply delete a synced item from the item itself and have to use the menu is beyond me. Very odd UX design.
