Backup Exec 2012 vs Restoring from DAG

Hello,

I want to test a restore of specific items in my Exchange mailbox, from the DAG backup I took.

When I go to the selection list, open my mailbox and go to "inbox" to see what can be restored, I have the following.  (look at the right pane in the image)

Clik here to view.

If I go down the list, I can still see some of my emails but what are these objects and what should I do with that ?

Thanks
