Not eligible to sell my character

[towelie]

I've been trying to sell a character I leveled for some time now. I enabled two factor authentication long ago but every time i try to put my char up for sale it says that I'm not eligible to trade characters. Is my account bugged? Or am I missing something? Anyone have any information or advice?
thank you
