Journals for Cancelled invoice are not flowing to GL

We cancelled an invoice, it is validated, accounted and shows as cancelled.  We ran the create accounting with transfer to GL Yes and Post in GL Yes.  It completes with no errors.  If I drill to Journal entries from the invoice, it shows the reversal of the original entry but those reversals are not showing up in the General Ledger.  Any help on where to turn to trouble shoot this would be greatly appreciated.
