I have changed my new top logo from 247X94 px as in the documentation to 165 X85 as I believe should be the right size (?). But in the top menu, the vertical dividers now looks strange running too long down. Is it something I have misunderstood, and can you please tell me what to do about it. In the demo the menu has a big fat text on top and a smaller one under it, but not on my fresh install. Why?
