Okay, you said this (bolding mine):
Like I said, this particular problem is connected to autoblogged. Dups are posted in uncategorized along with the category I chose for the posts.
You just said the problem was with Autoblog. Having NO idea how that plug-in works (nor, frankly, why anyone would want it...), my understanding was this:
When a post is scraped via Autoblog, it doesn't assign a category correctly and thus ends up uncategorized, annoying you
If that's not what's wrong, then you need to perhaps better explain what's going on. If that is what's going on, talk to the plugin makers for support, as it's related to their stuff.
