Customer uses Duplicate option on an invoice.

The duplicate comes through with a blank Tax field, and all edits to the duplicated record do not calculate tax - the Tax field remains blank.

Any rows ADDED to the invoice calculate tax fine.

Customer is in US, using Tax Templates. GL setting for Use Tax Templates for Tax Calculation is on. Setting for Combine Tax Templates from Items and Contacts is off, but turning it on had no impact.

Anyone have any ideas that will continue to give the benefit of the Duplicate, but also calculate tax?


Thanks in advance for any help!
