Are there two versions of The Art of Fugue's "Contrapunctus 6"?

[csimmons0]

I have an album that contains two tracks with the same name, "Die Kunst der Fuge: Contrapunctus 6." The first of the two is the "in stilo francese" fugue. The second is my favorite part of tAoF, but it doesn't appear to exist outside of this album. Does anyone know what's up with that? This is the album: https://www.amazon.com/J-S-Bach-Works-Organ-Volume/dp/B000QZZPS6
