Tax audit trail report - includes cancelled AP Tax Lines

Hi,

We are using R12.1.3. In AP, sometimes users incorrectly code Tax Lines against an AP Invoice Line, and then cancel the Tax line and create it again - for example, this was first coded to the T-VAT code, then that Tax line was cancelled, and the user created a new line, coded to F-VAT:

However, then when we run the "Tax audit trail report" report for the relevant period, for the T-VAT Tax Code, cancelled Tax lines appear in the output - for example:

That seems to me to be incorrect, because the Taxable Amount for the T-VAT rate is zero, not 916.94. The amount quoted in the report is for the F-VAT Tax Line.
