Dear Support,

my sellers account is: testuser_arkin
my Listings:
110277698653
110277548735

I had some trouble while listing / retrieving.
I can't choose any category. Instead there is "recently used" Antiques > Antiquities > The Americas. for standard. And I can't change that!
I did the GetCategory API Call, and got all categories back.
But if I try to use Business & Industrial within the category lookup, I get back "no matching category" . Even a lookup from category ID is impossible, its a blanked field.

is there a bug in my account?

I really like to change the categories. I have to list a variation of these listed items, but at the moment there is no way to configure a variation.
Is that another bug?

Cheers!
