I just made a sell, but my payment is weird, please help!

Hi guys, first at all, i’m new here so i’m not sure how payments work when i sell something.
I sold one of my items a few hours ago, its cost is $39, before the sale i had $22 in my balance, now after the sale i have $28, so basically i just got $6 by selling a $39 item. It is something wrong? Can someone from the staff clarify this please?

Also, i think my dashboard is not showing the correct statistics.
It says "This week’s stats:
You have earned $17.10
You have sold 1 items
Your last sale was $39 about 8 hours ago."

Thank You!
