Chaining unpack activities on one decision zone

Hi there. 
I was having this issue where I want to unpack three product from a mobile storage from one decision zone on a conveyor. They don't need to be removed in a particular order, I just need all of them to be removed. In the current state it seems only one product can be unpacked, and then the mobile storage moves to start another run with two products still in its cargo. At the moment the decision zone is flowing into a NC machine, but it does not necessarily need to be a NC machine after. Attaching a video of the simulation, and an image of the decision zone called 'Avlastningszon'.
