N360 Backup: Folders set to be ignored are still backed up.

The N360 interface is not very intuitive.  I want it to backup my iTunes songs, but not my podcasts since they're updated daily and there's no use to back them up.  So I set all the podcast folder to NOT be backed up.  However, N360 still insist on backing them up.  See attached snapshots for an example.

What am I missing?  What should I do different so N360 does not backup those podcast folders?
