What does this "2" on the list of posts in my "network" mean? How do I get rid of it?

I've gone down and loaded all the posts that this page will let me post, but the "2" doesn't clear away.

Probably a bug. Most folks likely don't look at "network" often so I haven't seen it often.
Now that you mention it that number is huge on mine so it shouldn't be much trouble to look into.
