Advanced Custom Fields – Register a category

Hello,

I want my post type (Article) to have a field with a category so I have made a field named category that has the field of Taxonomy attached to taxonomy term category which is wrong to do but there were no fields for category…

But all my category does show up which is good but they do not get registerd on the category list itself when I view the articles look http://imgur.com/Zs7qXQH

Which is the field that setups a registerd categroy field instead of a taxonomy??

Thanks
