NFT creator did not receive SOL after sale on metaplex

[yuriypasternak]

Hi all,

I have forked this project and set it up online on my Github page. It seems to be working fine right outside the box which is great.
I have tried to create my first test NFT which was successful too.

Then, my listed NFT was successfully purchased by a third person through the web interface with phantomjs. However, I as the initial owner and seller of this NFT did not get any SOL after the purchase and I can't figure out why.

Here's my test NFT address: 36D8aHRKh52uZy9LJZ9bByS4pW4hvzTKoLwFR97Zo9Hh
And this is the address of the person who bought it: 575Z2jfu3WFZ5FFSrcAvPJXoFFcS6tSXRXUk6jJxWt3d

I can see that the token was successfully transferred to a new holder. Would somebody please help me figure out what is set up wrong and where did the SOL go?

Thank you
