Forum style problem
 

I've recently used the Vb default style to start creating a new one on my test forum and this is the only style available.

When I download it and import it into the live forum the header image displays along with the active style and the colours don't change when I view it via admincp.

I used option 1 when downloading because it does not have a parent. Is this correct and if not why?

Why would the image display from the active style and from the imported style if they are meant to be seperate entities?
