Fix the Bread crumb bar part 3

Hi Yigit / guys, I am very sorry to see that without changing any code a problem has returned to my website that I thought we’d fixed here –
https://kriesi.at/support/topic/fix-the-bread-crumb-bar-part-2/

If you look at page – http://catenais.co.uk/wordpress/products/ and scroll down, a huge gap appears between the breadcrumb bar and the menu (title bar). This occurred before (see part 2 ) but was fixed, and now it has returned? Not sure why to be fair.

This is a ll of my custom CSS –

/* nav.main_menu {
background-image: url(http://catenais.co.uk/wordpress/wp-content/uploads/2014/09/quality-marks.jpg);
background-size: auto 60px;
background-repeat: no-repeat;
background-position: 50% 0;
}
.main_menu ul:first-child > li a {
line-height: 85px;
}
*/
h5 { color: #fe0000; }
.my-custom-image {
float: right;
max-height: 100px;
}
.my-custom-image img {
height: 60px;
margin-right: 70px;
}
.header-scrolled .my-custom-image img {
height: 35px;
}
.av-main-nav > li > a > .avia-menu-text {
position: relative;
top: 20px;
}

.widget_nav_menu ul:first-child>.current-menu-item, .widget_nav_menu ul:first-child>.current_page_item, .widget_nav_menu ul:first-child>.current-menu-ancestor {
padding-left: 0;
left: 0;
box-shadow: none;
background-color: white!important; }

.header-scrolled + #main .stretch_full.title_container {
position: fixed;
top: 91px;
z-index: 1000;
width: 100%;
}

.header-scrolled + #main .stretch_full.title_container .container {
width: 1130px;
}

.title_container { background-color:#d60000!important; }
#top .alternate_color.title_container .main-title a { color: white; }

.breadcrumb-trail * { color: white!important; }
