Urgent! whitespace appears above grid row only on mobiles (responsive)

Hi Kriesi team,

on mobiles whitespace appears above grid row. I can’t delete it.

This whitespace apears not on desktop devices. And it apears not if I use other elements like normal column or indiviual cell.

I tried to use the element “separator / whitiespace” with negative margin, but this solution shifts only the content of the grid row up and the whitespace overlaps the top of the grid row again.

Do you have any solution for me? Please help!

Best regards!

Robby

By the way:
Please consider, that I used the following css in my enfold child theme:

@media screen and (min-width: 1025px){
#header {
display:none!important;
}
#main {
padding-top: 0 !important;
}
}

@media screen and (max-width: 1024px){
.rob_header_zeile2, .rob_menu {
display:none!important;
}
}
