This is because you have added custom CSS that is forcing the desktop nav to appear, in addition to the expected mobile nav. If you delete your custom CSS it will appear correctly.

Check the CSS applied to #header .header-display-desktop.

thank you @paul2009yes, it is custom css,  to appear wells like template. if i delete the css it looses also the design, i assume. is there another colde solution to add on afterwards for this specific double appearance?

I probably made the mistake not having checked all contingencies after the customization, it was a surprise to me to have discovered this double up menu in landscape mode on another device.

You can add a media query so the CSS only applies to this selector on larger devices, as you have done elsewhere in your CSS.
