In the cost analysis the cost of each ingredient does not add up to the total shown in the contribution tree. In the snapshot attached below, the total should actually sum up to 8.97E+04, but it shows a total of 6.89E+04. What am I missing here?

Maybe you have negative costs (revenues) in the last process?
