Missing description of packages in YaST2

Hi, I don't have a description of almost all packages in Yast2 in OpenSuse 10.0 on AMD64. It doesn't depend on status. There are installed packages without description, as a not installed. When I tried to query package, with commad in example:         rpm -q cups-client -i complete information even with description was returned. Any advice? Tanks -- Bezecný Martin
