Produmex - restricted alternate Item selection | In Picking Flow, all items on the selected bin are listed

In the producmes picking flow, if pick on a specific bin, and you select the item, whithout the possibility for scanning. The System lists all Items, which are on the same bin.
We don't understand, why it is like that, because the items listed, are not even "alternative" items for the product, which we need to pick. This should be changed in a future version please.
