All patent application documents are individually paged. That is to say, the specification is from pages 1 to N; the description and drawings are from pages 1 to N; the claims are from pages 1 to N; the abstract of the description is from pages 1 to N; and the abstract and drawings are from pages 1 to N. Don’t worry about the page number of the downloaded application form. In fact, you can make a similar page yourself when writing application documents. The homepage must have a header, but subsequent pages do not need to be. You can also type the page number directly in the lower middle of the document.
