KDE language in 13.1

Hi, I've installed packages bundle-lang-kde-cs and bundle-lang-common-cs on a fresh install of 13.1, but there is still American English only available in Configure Desktop, see http://postimg.org/image/fliz3smdb/

I did restart just to be sure KDE noticed the new files (packages).


What's wrong, should I install some other packages?
Thanks in advance!
