Picking multi boxes

I have a problem with my model but i can't found the error. The model is about a warehouse and picking of orders. In particular, the problem is that when the transporter finishes to prepare and drop off the first order then it stops instead to prepare the next order. I try to look for the error but the token in the model seems working fine and there aren't error reported. WAREHOUSE AS-IS PRELIEVI.fsm

Check the following section of your Process Flow again.

Currently you are creating one token per item that needs to be picked. So why would there be a decide in the sub-flow? The token would only have one job: Make the picker load the one item it is assigned.

Either you don't use a subflow and use the Decide to loop back until all items are picked. In that case you need a counter variable that gets incremented after each pick, so you can know which item to get next and when the order is done.

Or you keep most of what you currently have and put the action that only happen once in the 'outside' flow.

The "Pick Items" activity should have "Run Tokens One at a Time" checked, so the travel and load actions happen in the correct order and not mix wildly.
