Windows Live Mail ; Saved emails with same subject line. Only the last one saved is accessible

So I sent out a group email for an event I am managing. When the replies come back, I move them to a folder for that event. When I go to review the replies, there is not a reply for each one I saved to the folder, but only one reply with the names of the persons who replied underneath the subject line, as well as two envelopes beside the subject line. (which made me think that more than one reply would be there)

BUT... when I open the email the only message saved is the last one saved.  How can I retrieve all of those messages that got  buried?
