Once more than one NIC or volume has been added to a compute profile, it cannot be removed.

Following is the form data submitted after trying to remove a 20G volume. The _delete is set to 1 so I guess the form data is correct. However, if I get back on the compute profile form after the update, the 20G volume has not been deleted.
