Problem with responsive navigation

Hi
On my desktop iMac, when I add too many menu items to the navigation (so that it becomes wider than the space between the logo and the search/cart icons, the navigation automatically switches to responsive and shows the responsive menu icon (3 waves).

I’ve tried reducing the size of the logo to allow for more space, but the menu keeps switching to responsive.

In the theme settings, under ‘header options’ there’s an option called ‘Header navigation responsive layout’ which is set to 1060. I’ve tried adjusting this but it doesn’t seem to make any difference.

In ‘General options’ the ‘Responsive layout’ option is set to ‘responsive’.

By the way, I’m using the Eshop template.
