The reason you are running into this issue is because I don't currently support an option to keep the file storage separate between libraries. They all share the same storage location. So if you import different versions of files with the same name into each library, you will just overwrite one version of the file with another. Adding support for "isolating library storage" is on my list of things to do in the next 2-4 months (the sooner the better of course). In the meantime, you will have to use different filenames for each library. As long as the song titles match between libraries, the leader/follower feature will work just fine. You can also use other fields to match up songs even if the titles don't match such as Song ID or the custom field. When song versioning is released (sometime next year), that will also provide a way to handle all of this with just a single library.

The other option (which you won't probably like very much), is to use a single library, and just backup/restore each time you want to switch libraries instead of using the switch library feature. This will be tedious to manage, but would get around the current limitations.
