OK this is even more peculiar, the missing descriptions only apply to those in the top layer of the file (which is called Junk and has always been in the root file of drive C). So if I look at the contents of a file inside the junk folder all the descriptions are there in all views. For fun I copied the entire contents of C:\Junk to D:\ and lo an d behold all views work including the top level files. Delete the old C:\Junk and copy back from D:\ and the same problem still exists with the top level files and folders. Strange huh?
