Interesting. I know nothing about the lit format. But perhaps those 20 lit ebooks never had DRM to begin with and so removing it, ends up with garbage? Have you tried loading them in some other software that reads no-drm lit to see if they can be read as they are? Just a thought?
Also, perhaps you have two different keys. I think you might want try rerunning the key generation tool after opening one of those books in the reader just in case, these 20 use a different key than all of your other books.
