I downloaded the iTunes update & now my music, videos & apps have all been copied. I'm showing 2 of almost (A few things aren't copied) everything & also many things that were deleted long ago have showed up on my iTunes. Anybody have a clue what caused this to happen? What would be the best way to correct this issue besides going through & deleting each duplicate individually, or using the "show duplicates" feature? I did a search & wasn't able to find anything that addresses this odd situation.
