I have 3 questions about the ending of the fork/join process.
I draw a simple process with a fork and a join node.

My questions are related with the ending of the join.

Question 1:

All the tasks forward to the next task well.
When i finish the TESTEFORK - task 2, the join node verifies that all the fork child are in the join and finished and advance to the next task, the TESTEFORK - task4.
And the TESTEFORK - task4 is marked as the active task (Running).

But the Join node continues marked as active (Running "to task 3").
Should not me marked as ended/closed, and only the TESTEFOR - task4 as active?

Question 2:
If i choose the option "Não" in the TESTEFOR - task4, the process returns to TESTEFOR - task1, but the Join node continues marked as active and running. 
Is that a correct behavior, or anything that i'm missing?

Question 3:
When i advance to the fork for the second time, the number of child of the Fork node is incremented to 4.
Is that a correct behavior, or anything that i'm missing?

Number of tokens in the first time that the fork node is used.

Number of tokens in the second time that the fork node is used.
