Class scrbook Warning: Usage of package `titlesec' together
(scrbook)              with a KOMA-Script class is not recommended.
(scrbook)              I'd suggest to use the package only
(scrbook)              if you really need it, because it breaks several
(scrbook)              KOMA-Script features, i.e., option `headings' and
(scrbook)              the extended optional argument of the section
(scrbook)              commands.
(scrbook)              Nevertheless, using requested
(scrbook)              package `titlesec' on input line 82.
