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/
2. You can go to Appearance -> Customize -> Additional CSS and use this code:
.header-7 .haru-header-nav-wrap .header-navigation .header-elements-nav.left {
display: none;
}
.header-7 .haru-header-nav-wrap .header-navigation:before {
left: 0;
width: 100%;
}
.header-7 .haru-header-nav-wrap .header-navigation .header-primary-menu {
margin-left: 0;
}
header.haru-main-header .haru-header-nav-wrap .header-navigation .menu-wrap .haru-main-menu > li > a {
padding: 0 15px;
}
If the code doesn’t work you need add !important follow this: https://www.lifewire.com/what-does-important-mean-in-css-3466876
