If you refer to the fact that the header is suppressed for the first page of a chapter: this is intentional (and is also what you usually find in typeset books). If you want to change it, try \renewcommand*{\chapterpagestyle}{headings} (but you won't get the chapter title printed in the heading, scan the KOMA manual for \chapterpagestyle for an explanation).
