UBB.threads PHP Forum Software Community Forums UBB.threads Version 7/8 Support Active Topics drop down menu

I just installed my 7.1 version and I'm testing it.
there are a lot of new good stuff on it. Thank you

Now, I notice that at this board, when you click the 'Active Topics' you receive a drop down menu:
Active Topics
Past 24 hours
Past 48 hours
Past 7 days

It is not showing up on my site.
Am I missing something ?

I have only one style "ubbthreads" on the style folder.
