Audiobooks appear duplicated in iTunes after update
Since updating to 12.7.2.58 two days ago, the majority of my Audiobooks appear as duplicated in iTunes. The files themselves don't appear to be duplicated, but when going to listen to Audiobooks within the iTunes desktop app, there are 3-4 duplicates of each book showing.
