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).
