Here is my PDF output:
Here is my master page when I preview it in Robohelp:
I've tried putting my line breaks in but I cannot get the text to move down. Do you have any advice about how to correct this?
Try margin above for that heading style.
I have found that if the heading is a heading 1, it displays correctly.
But if the heading is a heading 2, in other words, this is one topic that has run over 2 pages, then it does not display correctly.
I tried adding some padding to the header. Again, it looked fine in the preview but made no difference in the output.
In the Preset configuration look at Layout > Page Margin. Click the link icon and try increasing the top margin. I'm not sure but that might exclude the logo. Try it and post back.
