The token with the item label is entering the join activity through connector number 2, you need to ensure it comes into the join through connector number 1.

This section of the manual explains what is happening in more detail : https://docs.flexsim.com/en/19.0/ModelLogic/AdditionalConcepts/Coordination/#connectors

Only the token which came in through connector 1 survives.

This usually isn't a problem, since Join tends to be used with Split, so your child tokens (which exited the Split through connectors > 1) can write labels to the parent token (which left the Split through connector 1) when necessary.

In cases like yours, Join isn't really the best tool for the job. Instead I'd suggest you push your items to a list whenever they arrive. Then the tokens which are generated every 10 seconds can just pull 2 items from the list and transport them.
