Issue: Article History not updating

I'm not sure if this is an error on the Vaultwiki side or if this is a settings issue that I cannot find, but I got a report from one of my wiki moderators that the revision history is not updating properly on my site. Here is an example: http://www.runicgamesfansite.com/sho...ry&redirect=no

On that page's revision history it only lists 6 revisions, the latest being 07-18-2010, 11:15 PM. However, if you look at the bottom of the article it says "Last edited by , Today at 07:22 PM." It obviously knows there have been more recent revisions, despite that they aren't being saved. I also can't find any settings that let me control the number of revisions, though even if I did find one I suspect it would be supposed to count from the latest revision back, not count forward since the article's creation date.

Thanks as always for your help.
