Cannot remove item form exchange when reach maximum gold.

Cannot remove item form exchange when reach maximum gold (4,294,697,295).
it will trow this error "you cannot store this amount of gold"

You may likely be aware of the cause and it doesn't change the fact this is an issue ...

but the Exchange is trying to refund part of the gold you paid to list your currency offer, since it completed your trade without selling all of the currency you made available. You can't accept any more gold (without spending some first), so it prevents removing the completed trade and your currency from the Exchange.

(As I also posted here as others ran into the same problem. Not saying that it isn't awkward.)
