[opensuse-buildservice] Packages no longer existing / repositories not used

Hi, While testing some packages, I also added repositories for different other platforms. After deleting them, they seem to remain active for access via software.opensuse.org/download Is this normal behavious? Also the packages inside have not all been deleted, thus causing errors if I add for example the repository for SUSE-Factroy to my homedir (dimstar) again. Most packages don't get build now for factory. What did I do completely wrong and how to avoid it in the future? Also: can I exclude different thins from being built for a distribution like Fedora for example but still having the fedora repository for other packages? I'm sorry for the mess I might have created on the server. Dominique
