The operators doesn't pick the correct quantity in all Types

Good evening to everyone. In the attached model I build the following logic. Three Operators create 3 orders. Each one has a dedicated Gravity Storage Rack and its own PickingList. But there's a problem.

For example when the operator1 makes the order2 (pallet appearing at the 20th second) I put 10 pieces of Type 100 and 10 pieces of Type 105. The result is not correct because he takes 10 pieces of Type 100 and only 2 pieces of Type 105. I can't find the cause of this malfunction. I would appreaciate any help !

Thanks in advance.

It looks like the picking data is being stored on the label order_list on the parent token, but the child tokens are using data from the PickingListOperator1 table instead of the label table.

You'll have to reference the order_list label using token.labels["order_list"].as(Table) as token.order_list will just return the value of that node.

Also it looks like in Run Sub Flow - Order_list LOAD activity, you assign the child token the order_list label, which removes the ability for the child tokens to read the label table off of their parent without saying token.parent.labels["order_list"]

@Matt Long . Thanks for your advice. I understand that the mistake is that I use the global table PickingListOperator1 in the process of picking. I should use the labels of order_list. I tried to fix it but with no result. I always take false in the syntax.
