Header display issue

I have an issue with the Header image. The header image stays distorted no matter what size image I add. I’m using the latest version of WordPress and the 0.0.9 version of Cannyon. Is there an fix for this?

I cannot provide a website yet because it isn’t “live” yet as I’m still playing around with the Cannyon Theme. As soon as I get this issue resolved, I’ll provide the site for all to see!

Thanks!
