Subprocess inner multiinstance subprocess

I have a multiinstance subprocess in my process that I called it ‘parent’. In parent I added a new subprocess that called child. The collection of parent has 2 element. So I think engine must be execute parent and child 2 times but engine run parent 2 times and run the child 4 times. I think engine convert the child to multiinstance because of its parent. Is there any way to run sub process 2 times?
When I create another subprocess inner child, this subprocess runs 8(222) times!

Hi @Mohammad_Mahdavi
could you post your bpmn processes? this might help to better understand what you are trying to achieve.
