I've waited about 60 days for some bundles to get deleted, and they have not been. They were not associated with any devices (too old). When I tried to delete them, I get the following message (an example here):

This object cannot be deleted: MS07-040 931212 928365 929916 Security Update for .NET 00000440. Probable cause: The object is a ZENworks Server. To remove a ZENworks Server, please uninstall ZENworks from that server or delete the server object using the Server Hierarchy control (located on the Configuration page).

Obviously the bundle is not the Zenworks server, so why is it saying that?
How do I get rid of these items (there are 13 that all generate the same type of error).
