Not showing up in auction hall

[PEWLUVSCHU]

I was selling some stuff to my friend Another_Groovy through the auction hall ( One handed battle axe, leather gloves, and a kite shield )
He got the One Handed Battle Axe fine, although when I put up the kite shield it did not appear for him. It was there for me rho :\
he tried searching "Kite", he looked in shields, i gave him a link to the page it was on, nothing :-\
and then we went on to the gloves and he got them fine :\ Possible bug?

He most likely doesn't have the required class to use it, items you can't use won't show up on the Auction Hall.
