MIU MIU authenticity cards - help!

  1. hey girls!
    i bought a white leather miu miu bag from the dolce and gabbana boutique, but the authenticity card - there i noticed a typo - they wrote it once in italian and once in english - the english typo contained "umidity" instead of "humidity". i'm sure that the D&G boutique within department stores sell authentic goods, i paid a lot of money for it too, but am really concerned about the typo because it makes me wonder...

    does anyone out there know anything about this? thanks in advance!!
