[Koha] Two different withdrawn fields

[Dalton Fury]

Hola,

I see two different withdrawn fields for every item. One is a YES/NO field
found under status section of each item:

and other is found when you edit an item:

The second withdrawn field does not confuse me because as it is the one for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withdrawn field.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the other withdrawn field?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,
