I don't know if it makes any difference but I am using Calibre version 0.7.25.
I am also wondering if I am putting it the correct place: Structure Detection, header regular expresion, with a tick in remove header.
That's the right place. However, I cannot help you, without you providing some detail, in creating the right expression. What you need to post is the code (what you see when you click on the magic wand besides the header/footer regex) of the page numbers and headers/footers you want to remove. A snippet containing the offending entries and a little before and after suffices. However, I'd strongly suggest that you read the manual entries I linked to. I'll gladly help if you don't understand something, but you'll gain so much more if you learn to write the expressions yourself.
