Trade Items gone

At the beginning i put 2 items in my trade tab. Axiom Perpetuum and Summon Stone Golem of Hordes.
I was away a few days and now i'm back and the items in the tab are gone.

But there are many people that want to buy these things but i can't see them. And i can't put the tab on private because i get offers for the items anyway.
No matter if i put it on private or public.

I have no clue whats wrong and it's the first time having it.

I solved this issue at last but thx for the answer.
