Remove horizontal bar after content title and content

I use Wordpress MU, Buddypress and Enlightenment theme.
I follow your documentation at https://www.onedesigns.com/tutorials/enlightenment-documentation-theme-demo-home-page but I can’t find how to remove horizontal bar after content title and content.
In a preview image in “Changing the Page Design” section the bar still appears but it doesn’t appear in next content preview screenshot.
Please let me know how to fix it.
I'm paid user here.

Cheers,
Marcin
