Hello,
Apologies for the Inconveniences caused!
The Codes you are using are incorrect for the One Page Menus. Consider using the following replacing the old codes:
[ch_pre]
The Offset will set automatically based on the Sticky Menu Position or you can also define your Custom Offsets using:
[ch_pre][/ch_pre]
or Individually for the Menu Items:
[ch_pre]
Using the Above Codes should also close the Menus on Scroll on Mobile Devices. Consider check the Live Previews here: https://canvastemplate.com/op-index.html .
Hope this Helps!
