Freshness not updating on BBPress

Hello,
URL: http://yourtechadvisors.com/forums/
On this page, the BBPress freshness section is not updating. It says that there is 1 post in the boxed photo below, but when you go to that forum, there is not, because I deleted them. How do I make the freshness realize that there are no posts in the 2 forums?

EDIT: Screenshot is below.

Thanks, support access is open.
