MyBB Community Forums

Hi,
I'm using the 'tabbed menu' from mybb central, and when I install it it shows this, and when I add I added forums to go under the mybb section, and when I click mybb it doesn't show them?

How can I get rid of how it shows twice, once above and once below?
and how can I fix it, so it shows my other forums, as I did add the tab and the forums to the tab, but there not showing up..

You probably have to ask this at mybbcentral

There might be a problem with the template in the header where the menu is
