If the extensions are gone then there will be nothing there to allow you to make a policy as the policy settings are based on the extension you have installed. If they arent in the repository list, I'm not sure why they would be showing up under the policy catalog...
maybe it will help if I reinstall these extensions and remove them again afterwards.
Does anybody know where I can get these 3 extensions?
Issue is solved.
A Tier III supporter gave me a SQL script that was able to remove the faulty items from the policy catalog.
Thanks for all the replies.
