1. You have created (SAVE) your own Mod-File?
2. You are setting that file ^^^^^ as the ACTIVE File when you load your stuff into the CK?
(I can't think of much else that would do this)
If you aren't doing either of those, I'm not sure what - other than a reinstall of Skyrim and the CK - will fix it ...)
BUT: Maybe someone else has seen this behaviour before and can help you better?

(although, as this is your first post here, I doubt you are using Version-Control??)
