It worked finnaly... I tryed the Tree view in Coin control and it grouped the 2 lines in one line. I selected that line, I chouse the recomended fee, and it worked.
Prevoiously, I used List view, and selected only one line from the two, and used a custom fee. That didn't worked.
So... Coin control > tree view > select one box > transfer all available with fee substracted from amount  > recomended fee - 2 blocks > working!
