Yes, the d rights are supposed to be there.  In unix one always have
delete rights to files.  Whether you can delete a file is controlled at
the directory level.  That is, you need both delete rights on the file
and expunge rights on the directory containing the file in order to
delete the file.

If you like at it with the unix commands, you need not even know any of
this.
