.w-dropdown.source_qtranslate .w-dropdown-item-title {
background-position: 0 50%;
padding-left: 0px;
}

.qtranxs_flag_zh {
background:none;
}

.qtranxs_flag_en {
background:none;
}

.qtranxs_flag_KO {
background:none;
}

This will remove the flags, and eliminate the padding on the left where they would sit. Hope that helps!
