Laptop and Mobile layout different

Hi, i just updated sydney theme to its latest version for my website,

which I had not to change any layout or padding.
but I notice an issue on my website with some different on its layout when on Laptop, Ipad and Mobile.
notice those subpage ie:
the picture shown on the laptop is cover the entire row there are no blank spaces within.
yet when I check on my Ipad and mobile the picture has left some blank spaces.

besides for the front page/home page, the header usually shows for almost my iPad and phone screen for me to roll it down. but after the latest update, the header slider height becomes smaller

Wonder can anyone advise me how I can solve these issues?
very much appreciate your advice. Thank you very much!
