Removing a package inside Unreal Editor

[Dragatomic]

I created a package in Unreal Editor and by importing in a mesh and its animations. Now After I wanted to put in another mesh into the package I noticed that it wouldn't save the new mesh. I tried saving it and when I re opened it, the other mesh wasn't inside. What was weird was even after I deleted the UKX file inside the animation folder it would automatically load my package up even after I deleted it. How do I get rid of this package and stop Unreal Editor from autoloading from some unknown location?

If your using a mod directory setup, make sure you haven't saved it in the base animations directory

Well I'm not using a mod setup, I don't even know how to do that yet. But I saved the ukx into the Animation folder in the UT2004 folder. But I deleted it so why is it still showing up in Unreal Editor. Is this some sort of bug with the ActorX plug in? It is also auto loading the UTX I file I created. But is there a way to fix this?
