knight rider online

So I got the knight rider box set for x-mas and to my suprise I got 2 copies of the season 3 discs with the episodes contained on disc 3 and 4. SO I am missing a jewl case with the corrrect discs 5 and 6 in them. Has this happened to anyone else? My GF got them from sears online so I assume were gonna have to ship em back.

Although I don't have the boxed set, I think it's just a packaging error.Just call them and send them back for a new one.I wish I could be more help.
