Sum of repeating field not always updated

We have a repeating field, rejects[8].   A calculation field, sum(rejects[8]), does not always display the correct sum, but after a few edits of any of the elements in rejects, the sum is correct, and seems to stay correct with additional edits.  Is there anything we can do to force it to be right all the time?
