Something changed recently for me in iTunes, and now many songs in my iTunes library show up twice, with both local and available iCloud download versions:
I don't understand what caused this to start happening, or what it means. I'd like to make it stop. It seems to happen mostly to recently-purchased songs. I always use the desktop iTunes application to buy songs from the iTunes store, so presumably the behavior is not due to my buying songs on other devices. I'm using macOS 10.13 and iTunes 220.127.116.11.
How can I stop this double-listing from happening?
