Hi,
The problem in your model is you have used "Labe name: connector " This will return some values this is not matched with output port number. This is why the Transporter is not transporting the item.
For example Item Name: Mirinda Orange Mw. Glas 24 x 0,2 L will return the label value as "137". The problem here is you don't have a 137th output port to transport This Mirinda Orange Mw. Glas 24 x 0,2 L item using operator. This is the reason why the operator is not transporting the items. Below image 1 will illustrate your problem

This problem can be overcome by send item by "Port By Case". I have built a sample model using your 5 Item name and its quantity and I use Lable call "connector". This label will be used in Port By Case to transfer the item using an operator to respective Queues .I have attached a sample model and an image 2 for your reference have a look at it.

Thank you
