Autoblog - Add Posts To: field missing

Just installed the Autoblog plugin but it looks like I'm missing the field called "Add Post To" when adding a feed.

According to the installation directions you can activate this plugin site-by-site if needed. I tried Network Activating the plugin but that didn't work either. So, if I have it only activated on our main site, I should be able to send the feed posts to any other blog, right?

What am I missing here?
