Problem with removing an element from an array

So I’m trying to create a trade system, all items are stored in an array of structs. I have 2 widget BPs and each time I click on a button (All items), there is a loop that adds each item to a scroll box.

The problem is when I try to buy an item (remove it from the array). I do so by clicking a Buy Now button and the item is indeed removed from the array. However, only the current item is removed, and the array is not updated with the previous removal. Furthermore, when I click on the All button, it shows all items again.

Does anyone have an idea why this happens?





Thanks in advance.

For some reason, the problem is that I’m removing the item from the child BP. If I remove it from the parent BP (where the array is defined), it works correctly.
