Menu items

Hello, I’m having a few problems. Please help. My page titles appear at the top of the page as well as in the menu bar. I only want then to appear in the menu bar. I go to Appearance>Menus, but can’t find an option to disable. I would also like to change the CSS. On the Expound theme support page there is an option to go to Appearance>Customize>CSS. This is another option I don’t have. Can anyone please tell me why? Do I have to upgrade to have these options?
