Code editing issue

Hi, my blog is located at https://www.candacemarra.info. I am using the Karmela theme, a free theme that, unfortunately, does not offer support. I was hoping maybe someone here would know enough about coding and/or scripting to answer my question.

If you look at my blog, everything looks to be in place with the exception of the navigation menu at the very top. There is a black bar that is supposed to go all the way across the page in one straight line, but there is a large break in it right through the middle. The links (Home, About, Contact Us) and the RSS and Twitter Icons, are located just below it, making it difficult to notice the links at all. The links and icons are supposed to be right in the middle of the dark bar. This is how it looks in the original template. Of course, when you look at the demo of this template, it looks broken up like this there too, indicating a coding problem rather than something I did. Does anyone know how to fix this? It is driving me crazy, but I really like this template!
