Exporting my windows live mail contacts to a file, I found on reading the file I had two contacts albeit name only and no email addresses. They do not show up when looking at the address book. This is in windows live mail client on my PC. If I access outlook through explorer they are not there. I have cleared out all my contacts downloaded from the exported copy after deleting the two hidden ones but they are still there if you export again.

 

By any chance, did you resolve this issue in the end? I seem to be plagued by it too.
