If you move items around using JSWED's GUI - i.e. by deleting it from the old location (above the cross) and re-adding it at the top of the ramp - then in the intervening period, JSWED will have shuffled all the other items from earlier in the item list to 'fill the gap'. Then when you add the item again, JSWED will put it at the top of the list.
So that's probably what's confused you?
If you get a 'fresh' copy of JSW and apply the POKE I provided, then it should do the trick?
