Status when cancelling an order.

Summary:

I canceled an order with line status "Awaiting Shipping", and now there are two orders with revision 2.
One has a header status of "Reference" and a line status of "Cancellation Requested", and the other has a header status of "Processing" and a line status of "Cancellation Pending".
What kind of situation is this?
How can I change the line status to "Cancelled"?
