Purchased music showing as "Matched AAC audio file"

I know this is nitpicky, but some of my iTunes Purchases (songs actually bought and downloaded to my computer) show as kind "Matched AAC audio file" instead of as kind "Purchased AAC audio file".

The problem only happens when iCloud syncs. If I turn off iCloud, all the "Matched AAC audio files" change back to "Purchased AAC audio files" (which is what they are).

Why when I'm connected to iCloud are my purchased songs showing as "Matched". I know it's maybe not a big deal, but just so frustrating and doesn't make sense to me.
