Modules are hiding under the menu bar

Hello,
After updating to Joomla 6, the modules are hiding under the menu bar.
The custom.css file contains:
@media (min-width: 1400px){
.c-offcanvas--left {
margin-left: 25px;
}

.horizontal-nav::before {
height: 100%;
background: var(--horizontal-background);
content: "";
position: absolute;
right: 100%;
width: 20000px;
}

.horizontal-nav {
left: auto;
}

.t4-content {
padding-left: 0;
margin-left: auto;
margin-right: auto;
}
}
.google-maps { position: relative; padding-bottom: 50%; height: 0; overflow: hidden; }
.google-maps iframe { position: absolute; top: 0; left: 0; width: 100% !important; height: 100% !important; }
