Hello,
1. Looks like there is a bug with this cart icon. You can change the icon in Theme Options > General > Header Settings > Shopping cart icon or add this code in Theme Options > Styling > Custom css:
.shopping-container.ico-design-1.ico-bg-yes .cart-bag, .shopping-container.ico-design-1.ico-bg-yes .cart-bag:before {
border-color: #000000 !important;
}
.shopping-container.ico-design-1 .cart-bag {
opacity: 1 !important;
}
Background you can disable in Theme Options > General > Header Settings > Icon with background.
2.
.fixed-header .my-account-link {
margin-right: 20px !important;
}
Regards
