I'm assuming you used Import->Batch Import, and you also enabled the option to populate metadata based on the subdirectories. I'm going to need to know what metadata format string you specified, as well as an example of the folder structure of the classical folder that you imported. If you had %GENRE% as the first value, then you should not have batch imported the contents of the Classical folder - you should have batch imported the folder above that folder, so that the first folder it encountered was "Classical". If you imported the contents of the Classical folder, that means it instead used the folders inside the Classical folder as the genre for each song that was created.

On a side note, you can revert the library changes under Settings->Backup and Restore->Restore Automatic Database Backup if needed, but that will revert all changes to the last point a backup was created.

Thanks,
Mike
