iTunes match to dumb to see duplicates??

iTunes match in theory is a great idea, but I find it frustrating at times. I have an album I purchased and for some reason there is duplicates in iCloud of the album. I cant seem to get rid of the duplicate, they are all the exact same name song length, etc, so an exact duplicate. Isnt iTunes match supposed to detect duplicates and get ride of them?! What can I do to get rid of duplicates in the cloud?
