There should be option to remove used item from Random from list asset.
That is, when you pick up one item (action Select new item) and use it, there is possibility that next time you ask for Select new item you will get the same item, or not. There is no guarantee it will not repeat already used item if you ask multiple times for new item.
By removing already used item, you make sure that next time you use Select new item you will get non-used item.
