[Koha] Two different withdrawn fields

Hola, I see two different withdrawn fields for every item. One is a YES/NO field found under status section of each item: http://imgur.com/a/j8lvv and other is found when you edit an item: http://imgur.com/a/s5g6y The second withdrawn field does not confuse me because as it is the one for which I have set authorized values. But I cant see why there another YES/NO withdrawn field. How and when is it set? How does it relate-to/differ-from the other withdrawn field? Regards, Navaneeth
