unable to restore iTunes older backup

I got 2 backup files in iTunes, the older one is what I back up when I change my iPhone5 to iPhone6 which was successfully restore my files.

And there is an other newer one with no date, not sure if it is created when I restore my old iPhone5 as new, there are none of my data in this back up, but I accidentally restored my iPhone6 with this yesterday.

I tried to click restore with the older back up, but iTunes occur an notification said unable to restore my iPhone because an error occur, there are no error code.

How can I restore my data with the older back up?

Please advice.
