AGV does not travel to queue when using pull strategy

Hi, I'm trying to make a loop system with 3 AGVs and 2 queues (without sink to check the quantity of items). And plus, want to apply a specific pull strategy from exit transfer to queue (refer to attached file). Using pull strategy seems not properly working in this model, so I need a help.

Here's the problem.

1. There are 2 sources, 2 conveyors(from each source), 1 circular path, and 3 AGVs. Sources creates 4 types of item (label: type). Type 1&2 should be arrived at Queue 1 and Type 3&4 goes to Queue 2.

2. In this case, what function should I use? thought it was pull strategy (or global table) but I couldn't make it up.

3. It would be the best if it can be solved without any custom logic.

You can either use the "Port By Case" option in the Send to Port field of the Exit Transfers. Or you activate the Pull behaviour on the queues and use the "Range Of Item Label Values" option in the Pull Requirement.

It is always good if you could attach your model to the question. That way we can have a better idea of what you already tried and look for specific problems that migth prevent the model from working.
