Help with two minor issues

I’ll start with a link to the website that’s still in development:

Here

My two problems are:

When I change the header color from the “customize” menu from the dashboard, it doesn’t cover the entire page header. I was wondering if there was a simple way to target the rest of the header using CSS?

Secondly, for some reason my menu dropdowns: “properties” & “things to do” cannot be clicked through to the page I created for them. “Galleries” is not a page itself, just text to place the picture and video galleries under. I have no idea why I cannot access my “properties” page or “things to do” page.

I know there is theme support, but I don’t have access to the themeforest account to register the product. Any help would be greatly appreciated.
