Let me explain the issue, I have background for second section which have graphics only on left and right edges which is not showing mobile view. So i created new section for mobile with background according to mobile view and display none to desktop section.
Now problem, im facing is the menu which scroll user to particular section is not working as it is defined two times in layout.
So now if you check the website you will see it is showing the white part of image only in mobile as i have enable the desktop view and display none to mobile view.
So, it can be fix by either show different background on mobile and desktop or by fixing scroll section issue.
