why can I not delete items from the library?

[philipm44268848]

I try to delete items but when I later attempt to transfer new items the, supposedly, deleted items return and will be transferred instead of the required new items. I have removed Digital Editions and re-installed but this has no effect. Can anyone help?

Do used Windows or Macintosh?
