Blog Layout

Hi

When I view my blog it only shows 10 articles but I have a total of 22, can you advise how I can show them all – http://gc.osx.uk/latest-news/?

Also when I view my website on a 13″ laptop screen the logo is on one line and the menu items on a second line as per this screenshot – http://gc.osx.uk/wp-content/uploads/2018/03/Screen-Shot-2018-03-26-at-21.59.52.png. Can you advise how to fix?

Thanks
