Itunes Version 220.127.116.11. I connect my iPhone to iTunes and select Music on the left side of the window in order to select music to sync. The area on the right of the screen titled "Artists" shows some of the artists more than once. This is strange. I recently added those artists to my library. All the older additions are listed normally. Any ideas why some artists are listed more than once?. My library is housed in a QNAP NAS.
