Job Cost Report Missing Entry

On the Job Cost Report for one of my jobs, the Subcontract total for a specific cost code is missing the amount of one invoice.  The invoice was correctly put to the corresponding Commitment.  The correct amount shows up on all other JC reports.  But for some reason it's as if this one report did not get updated. I even re-posted the invoice by changing the accounting date to see if it would refresh but that didn't work either. Any ideas why an entry wouldn't post on one report but show up in all the others?
