We have recommended you to either set your website logo or site title and tagline.
As per our theme standard, we consider logo height or title and tagline height but in your case, your menu height is more than we have set in our theme.
So to overcome this issue we will provide you custom CSS for the mobile device but it will break in other screen resolution.
We provide custom service, if you really want to continue with both logo, title and tagline.
We will provide you perfect solution for all the screen.
