TOPIC: Unable to change the order of the cost calculation

If I make 10 new events with the repeat 10x function in the source event I get one first event and 10 children one level beneath the first in the list.

This is nice so I can expand or collapse the list easy.

BUT:

I can't change the costorder in the children anymore because there is no button to select this in the list

AND I think changing the order in the first event does not work properly or not at all. Is this order FIXED at the moment of duplicating or what??

It seems that I cannot change or correct things as I can with normal individual events. I this true? Is this a BUG or is this expected behavior???? I hope not....
