Header background with transparent and shadow

Hello my friends,

Before update to 4.4.1 I had this code

.html_header_top.html_header_sticky #header {
position: fixed;
box-shadow: 2px 2px 2px 0px rgba(0,0,0,0.5);
}

and this another

#top .av_header_transparency {
background: rgba(0, 0, 0, 0.5);
}

To create a shadow on my header transparency but now before updating I have a problem because I can’t see the shadow and that is very important to read the white header.

I send you private access.

Thank you so much
