Dashed Line appearing in output

I have a job that renders a dashed line at the top of a page (looks like the “border” of the default P element). That line isn’t in the design or CSS. How do I resolve this?

I had an issue similar to that and it was from the table so by putting transparent colour to borders I fixed it.
There is an issue at the moment where borders with width = 0 still display a tiny line and that’s the way to workaround it.

What’s appearing is the “border” around the default empty paragraph at the top of the print section. This print section has no other content (all content is set by the Background Image and a Master Page).

If I type junk into that paragraph, save the template, then backspace the nonsense text away and re-save, the problem goes away.
