How do you fix a problem with the ledger close where only one journal is generated?

Client performed the ledger close for the fiscal year. The Closing Rules have the generate journals checked. The closing created entries in both 999 and 0, but only created a journal for period 0. They want to be able to see both journals.

We ran the undo, but that only reversed period 0. The amounts posted to period 999 are still there.

How can this be corrected?
