Chopin Nocturne Op 9 No 2. Which is the correct version?

[ttttrigg3r]

Hello all,
Quick question about Chopin's Nocturne no 2. I started learning this with this sheet music linked below.
https://www.8notes.com/scores/11399.asp

This one has the first left hand notes as an octave Eb.  On about every tutorial videos and all the other sheet music I've found online, it starts out with only 1 Eb, not octave. Which is correct version?  
Even though I am still beginner, I want to make sure I learn the complete version and not an easy abbreviated one.

With Chopin, it is often difficult to determine the 'right' edition, but it is best to start with authoritative sources for what might be correct, or is generally correct.  Part of the discrepancies is due to early editions being published almost simultaneously in multiple countries which have some differences.
But start with valid sources and you will be 'close' to what Chopin intended.  8 notes is not one of them.

There are two good sources for free, early Chopin.  

imslp.org.  If you are not familiar with this website, let it become your friend as you look at scores.  Multiple early editions, not just for Chopin but for all music in the public domain. Free.

Some of the editions on imslp.org: Mikuli was a direct student of Chopin; although not THE definite edition, it is well respected
Cortot
First editions

The other source for free early original editions is
https://chopin.lib.uchicago.edu/chopin-catalog/

In none of these am I finding that the Nocturne contained octaves in the base.  Shame on 8notes.
If you purchase Henle editions, you will find not just the decision that Henle made when editing but a discussion about the different editions and why they made the choice they did.

Tutorial videos are not your base source for 'correctness' either.  At least look at authoritative editions to look for accuracy... then you can make a decision that has support

I've never seen this octave version until now, so i'd suggest against it. I believe I have the Wiener Urtext edition, and in that I remember there being 2 versions of this Nocturne scored, one as the "original" and the 2nd as a collaboration of all the 'authentic' changes that Chopin was said to have made on his students scores and republications containing various additional embelishments.

That version is ... here I think

Worth mentioning you said you're a beginner, I think this piece is aroune grade 5, so take that into consideration as to whether you're definitely ready

Thank you all. I stopped my piano lessons after 6 months and stopped playing 2 years ago. I'm just getting back into it now. I don't have the time and resource to put into piano because it's not my main instrument. I do love this piece, however, and I think I am capable of learning it. It might take me longer than most students.
