Cloud Icon Showing were files have already been downloaded

Have over 17 thousand files spread over different drives and different types of media files. But little over 500 hundred of these files still show up with the cloud download icon next to them in iTunes. But what is even stranger is that when I look at family downloads and choose myself and then filter not in my library none of these files show. But if I filter All files then these and others show up. I can continue to download them time after time. the cloud icon stays and if I look in finder I have version 1 2 3 etc.
