The list on the left displays an aggregate of objects by type and name. The assumption is all objects of the same type and name should be restored from the same snapshot. Objects not listed have no snapshots.
You will need to make a selection for each object you want restored. Objects not having a snapshot selected will not be changed.
Select each object to view a list of snapshots taken of that object. Select the date of the snapshot from which you want to restore.
Select next to view a detailed list of what objects will be restored by each selected snapshot.
