Trouble with programming Shelf Trolley [Need Help]

I've been working on a shelf (multi level) trolley a lot recently. I want my operator to somewhat "intelligently" unload boxes onto that trolley. Boxes are of different sizes and once one level is filled, he starts to fill another.

The operator fills the first level properly, but once he starts filling other, something goes wrong. I cannot find the mistake.

@EDIT

I've managed to make operator fill shelves one by one. If you take just one kind of a box, he positions them perfectly. The problem appears, when there is more than 1 type of box. You can see clearly what I mean in the file. Do you have any ideas how to improve the process?

@Maciej Kotlicki, is the limitation on uploading sketchup models because they are confidential, or did you have a technical limitation with this Answers platform? .skp files should be allowed for upload. Are your models of a different file extension?

Another way to post everything you need to, no matter the file type, is to archive your files into a .zip.

We're still looking into this. Quick question though, I noticed that the shelves of your trolley are queues. This will be problematic if you intend to move the trolley later on. Queues are what is considered a "fixed resource" meaning that it generally not meant to be moved in FlexSim.

Instead what you might want to try, (if moving the trolley is needed later on) is to have the shelves be "pallet" flow items, and have the trolley be an AGV or something. Or even, don't have shelves as items, but just as background part of the 3D trolley model, and just take into consideration the items' locations as you create stacking logic for it.

Here is a post with an answer from Brandon, that shows an example of how to use Pallets as shelves.

And here's a post from our old forum that shows an example of using a packing method,
