Number of packed items isn't visually correct, why?

[ FlexSim 21.0.6 ]

After using a sequence of operations for packing Items, at a certain point (specifically after the second combiner) the third combiner does not show the correct count of Items visually but the count in the Model tree is correct. In the attached images we see that the number of the packed Items in the receiving conveyor is 7 meanwhile it is 56 (7 times 8 packed items) in the model tree. Is there a way to fix this or is it a simulation bug?

It is a matter of location. Your items are place inside another. They aren’t any physical objects in your simulation. You must set different locations for them to see them all. It is not a bug!

@Joerg Vogel How can I do that? I tried changing the default's script of packing method but it only changed once, the next combiner of the line still had the same problem. What's the logic behind subnodes an location of items?

Any item, which is entering a combiner through input port 1, is the container. If you change the container item, as you did, in your model, then each container item needs a packaging method.

My attached example shows what happens if you change or keep the container item. I did not use a packaging method. I set the location of the new packed item in relation to already packed items in a trigger of each combiner.

The sequence of packaging is black box, cylinder, sphere, red box.

Left stack is the result of changing the container. Right stack keeps the black box as a container.
