In our theme have a notice that Page Options will override Theme Options. You can understand more about it follow this topic:https://harutheme.com/forums/topic/why-theme-options-doesnt-apply-changes/
So you need Edit homepage then go to Page Options at bottom of page to delete Canvas Sidebar element: https://prnt.sc/sa5i3d
So you can turn all options in Page Options to default to use settings in Theme Options -> Header -> Header Elements.
Hope this help!
