Cancelled confirmations without cost

This is the confirmation list from the PM order. You can clearly see that the total hours are 0
and that confirmation #2 cancels #1 and confirmation #6 cancels confirmation #5

In KOB1 the cancellations  number #2 and #6 do not exist even though I can see them as confirmation
cancellations in the PM order. You can see that it goes from #1 to #3 and from #5 to #7. As a result there is a cost of 302euro, which is essentially the cost of confirmation #1 and #5.

You can see the cost in the order. There is no cost from material or PO neither has there been a direct FI entry.
