New reply icons not showing up properlyFollow

Hello. I've been noticing a small problem with the White Mage job boards where new threads and threads with new replies aren't being marked properly with the correct icons.

For instance, this morning there was a reply to a thread at 8:20 am, I haven't visited the boards since some time last night. However, instead of the "New reply, and 10+ total posts" icon, it simply showed the "10+ total posts icon."

I've been noticing this issue the most on the WHM boards, though I don't visit the other job boards often enough to know if this happens there or not.
