Hamburger icon problem on mobile

Hi,

I am using one of your themes-full frame.
First of full great theme really customizable. It works almost perfectly. Only one problem I found out last night. When I go on my website on android mobile, and click on the hamburger icon, it takes me straight to the home page, like leaves me no time to select other pages on the menu, it’s kind of like a home button, even though the menu will slide in from the left but still leaves me no to select anything, just take me straight to the home page. But on iPhone and laptop it works just fine.

Do you have any idea why?

Thanks a lot,
Jason
