Ultimate team, trade pile players listed do not show up on xbox 360 or the web ...

i have this problem of fifa 11 ultimate team, on the trade pile. When i put players on auction for whatever amount of coins, then search the criteria of the item/player i just listed on the trade pile, the player/item does not show up anywhere on the xbox 360 or the web version of Ultimate Team, and in this case, if its not fixed, then i cant sell anything in the trade pile, therefore i wud lose all my future coins. what is wrong?
