[Upfront] Burger menu drop down customization

Hi,
I have a website with menu.
On mobile phones I wish to show burger menu to leave more space for content, therefore I chose Triggered menu style , with Center alignment and Whole for Show on click menu location. Everything fine until here.
When I tap on burger on a mobile device, menu shows and the first menu item (Home) which is under the finger at that moment is selected every time. How to de-tour this "autoselection"?
Thank you.
