This thread displays 11 posts and not the copmlete thread of 13 posts. Is there a setting on my profile I need to change?

If you look in the box at the top of the thread where all of the posts appear in a summary style, you can click on the link at the bottom that says "more replies below current depth", which makes me think that somewhere in my forum profile I have a maximum number of posts that I want to be shown. Still, I can see some other posts with 16 or more replies just fine. Could this be a index issue?
