Yast Online Update (YOU) - already installed patches showing up

Another strange thing I've recently experienced (possibly related to adding the KDE 3.2.3 supplemental update source) is that old YOU updates are showing in the package list. They aren't selected by default, and most of them are the exact same version number as what's currently installed. Is there some way to "synch" YOU with what's already on the system so I don't have to scroll through 5 pages of bogus updates to see what's new? Steve
