Recent downloaded albums duplicating

Try signing out of the iTunes Store then sign in again. This usually resolves any cloudy duplicates. In rare cases you may want to hide a purchase the persists in showing in the cloud. See Hide and unhide music, movies, TV shows, audiobooks, and books - Apple Support.

Have you tried signing out of the iTunes Store and then back in again yet?

If you've done that and you still have duplicates showing then see this post; Re: Deleting duplicate tracks.

It seems my duplicates are albums purchased from iTunes, can you tell me if I should delete these albums first from my library, thanks for your help
