YaST: resetting to defaults

How can I reset yast’s httpd module to defaults. I have copied default configs to /etc/apache2 and removed /etc/sysconfig/apach2

But when I start http-sever module it digs old configs from somewhere and over writes those that I manually changed.

On one occasion I had to uninstall apache, rename /etc/apache2 to something else (as a backup) and reinstall apache to get the original defaults reinstalled.
