Waltz No. 2 Op. 34- Chopin

[Glissando]

Okay, I downloaded the music for this off iTunes (it's performed by Claudio Arrau), and LOVED it so got the music from sheetmusicarchive- but they don't seem to match up. The both say 'Valse Brillante No. 2" So they MUST be the same, but the music just looks different.
What's up with this?
Probably me, right?

Okay, I found the right music for the recording I have- on sheetmusicarchive it's marked as Waltz, Op. 34, No. 1.
Now going back I realize that the music recording is marked "Waltz. no. 2 in A flat, op. 34 no. 1"- "Valse Brillante."
I'm still confused but I have my music so I'm going to go practice it now.
