Strange mobile menu

The first symptoms is when browser’s size is smaller occupies an area.
Therefore, it is possible to scroll x.

so
First. I add in css this code

html{
	overflow-y:scroll !important;
	overflow-x:hidden !important;
}

but was not fixed.
Second, i add in avia.js this code

$("#advanced_menu_toggle").click(function(){
	$(".html_mobile_menu_tablet #mobile-advanced").css("display","block");
});
		
$("#advanced_menu_hide").click(function(){
	$(".html_mobile_menu_tablet #mobile-advanced").css("display","none");
});

and. Second question.
sometime, scroll is impossible like this avi
