Linux home dir has a "duplicate" under /home/music but when anything is deleted from one it disappears from both -- how can I delete 2nd home dir?

I don't know where the 2nd "phantom" home dir came from. Properties folder shows it's 4K. The "real" home directory is 128,000+ files and 208GB. User10489 had the answer: a symlink directory. In fact, using the ls -l he suggested, I found a second directory that was also a symlink. I used rm to remove both. Thank you.
