Bug in number of posts on main forum page?

[halpern]

Hi all.  I am new to SMF.  I have to say I love it so keep up the good work. I do have a question though and this is not an advertisement.  It is just hard to explain.  If you go to my new site http://www.theofficeforum.net/ you will see that the Season 1 forum contains child forums.  If you look, one of the child forums is called Pilot.  Now there are two posts in that child forum.  For some reason, the main Season 1 forum is showing 0 posts and 0 topics but when you click on the Pilot child forum it lists the posts.  Is this a bug or is it just a setting I have set wrong?  From the outset it looks like no one has posted in the Season 1 forum but they have.  Let me know.  TIA
