Bottom overlapping onto header of next page

[ghost]

I have an issue where the bottom of the page overlaps onto the next page into the header. The amount is variable, some pages overlap more than others.

Below are the settings I use and screenshots attached. Any help would be appreciated.

var doc = new HtmlToPdfDocument()
{
GlobalSettings =
{
ColorMode = ColorMode.Color,
Orientation = DinkToPdf.Orientation.Landscape,
PaperSize = PaperKind.A4
},
Objects =
{
new ObjectSettings()
{
PagesCount = true,
HtmlContent = html,
WebSettings =
{
DefaultEncoding = "utf-8"
},
HeaderSettings =
{
FontSize = 9,
//Right = "Page [page] of [toPage]",
Right = "",
Line = false,
Spacing = 0
}
}
}
};

Some text is also being cut off on the right hand side.

Looks like the overlapping can be fixed with some css...
