Thread titles bolded

Don't know if this is just me, but when I look at the main page of the forums, on the right where it lists the most recent topic in each section they are all bolded as if there are new posts in the thread, even when I've read them all.

Just a bit misleading that is all!
 
I find this on other forums, hitting the refresh button seems to deal with it most of the time!
 
As Mike said, this happens on other forums. I think this is an issues with vbulletin.
