Reply To: Header banner not showing on Product Category page

I added a hack CSS code (see below) to fix that issue but I prefer the right way from theme as this header banner is a built in feature of theme.

body.archive .website-wrapper {
position: initial;
}
body.archive .website-wrapper header.whb-header {
position: relative;
}

I have now taken this code out so you can see the issue as well.

Please advise.
