The last icon means no activity since your last visit date.
This indicates the system believes those threads are actually read, or have expired based on your last activity.
For example, you sign in around 2PM CT but get called away from your pc immediately after signing in at 2PM CT. You are aware from your pc for 30 minutes. When you return at 2:30PM CT, all posts that previous were shown as unread when you logged in around 2PM CT will now show as read - even if you didn't physically read them.
This is because vBulletin forums, by default, have a cookie timeout feature that is used to determine when a user has become inactive and determines the last visit date - which is used to determine the if there has been new activity in a thread since your last visit.
I can't recall exactly what setting Corvette forum is using, but I'm guessing it's between 15-30 minutes. This means, in basic terms, that when you log in, a timer starts counting down from 30 minutes (if the setting is 30 minutes). Each time you click on an internal link while still logged in, that 30 minute timer is reset back to 30 minutes. Once you stop clicking on internal links, or you move away to a different website, if 30 minutes passes without activity on the CF from your account, you are determined to be inactive and the last visit date on your account will be updated with the last time you physically was active on the forum. All posts before that time/date will then become marked as read.
I hope this makes sense as it's my words while trying to describe how the system works and has worked for some time.
If this doesn't help, please provide some basic step-by-steps that you do that result in this issue so that we can see what is triggering it.
