History lists everything newest first. Each card shows its form, period, and key numbers: Total / Paid / Remaining, or old and new balances for month-end.

Open Double entries to see the exact ledger lines behind it.

Press Edit to fix. The form reopens with your values. Saving deletes the old lines and writes new ones, and all balances and reports update together.

Note: fixing an old month changes future Expected numbers. If real cash was affected, re-confirm that month.
