Autoblog plugin not pulling in site specific categories

Hi, I want to set up a feed for Autoblog in my Network Admin account for one of my sites in the network. When I select the site in the “add post to” field in the “new feed” form of the plugin, the “assign posts to this category” field does not pull in the categories from the site I’ve selected in the “add post to” field. Isn’t it supposed to pull in the categories?
