How to remove white space above transparant header

Hi,

First of all, excellent work with the theme. I worked with a lot of themes but this is the best, by far!

I have a problem now, there is a glassy header on my website but when I make the website fullscreen it get’s a 100% white bar above. I don’t know what caused this. This is my custom css but I don’t see anything off there?

.iconbox_content {
min-height: 250px;
}
#top .logo, #top .logo a{
display:block;
height:140px;
width:500px;
position:absolute;
left:20px;
top:6px;
border: none;
padding: 0;
margin:0;
z-index: 10;
}
.header-scrolled .logo img {
height: 30px;
margin-top: -1px;
}

.av-tt-hotspot, .av-tt-hotspot .avia-arrow {
    background-color: #35a4dd!important;
    color: white!important;
}

#top .av_header_glassy.av_header_transparency #header_main {
background-color: rgba(255,255,255,0.6);
}

.av_header_transparency .av-main-nav > li > a > .avia-menu-text,.av_header_transparency .sub_menu>ul>li>a {
  color: #195d84!important;
}

Thanks a lot!
