I am using an iPhone 6S with iOS 9.0.1

I'm trying to download some of my local files to my phone offline, but Spotify automatically switches some of my local files to piano/karaoke/cover versions when syncing to my phone.  For example:

Taylor Swift - You Belong with Me switches to... Taylor Swift - You Belong to Me (Piano Version)

Train - 50 Ways to say Goodbye switches to.... Train Ride - 50 Ways to say goodbye

When I play the files from the playlist in Spotify on my PC they work just fine but if I play the same file from my phone it is the other version.

I've tried...

Deleting and re-syncing files

Removing the files from the playlist and re-adding them from my local files

Nothing seems to be working... I'd rather have the original song.  How do I fix this issue?

Thank you
