Troubleshooting
Why a historical rate is absent from the live mapping list
A deleted or replaced WooCommerce rate may no longer be in today's tax table even though old orders reference it.
Inspect the source record
Find an older source order with the rate ID and compare it with currently configured tax-rate rows.
Build a focused report
Review the historical mapped-rate entries in TaxPack and keep a verified classification for IDs still used in past data.
Read the result
The tax-line CSV can reveal an old ID that needs investigation even if the live configuration no longer shows its original row.
A concrete example
An order from last year can still reference rate ID 14 after a new import created replacement ID 67.
Avoid this mistaken conclusion
Do not infer the old ID's meaning from the replacement row alone. Preserve configuration history when available.
