PP EC errors 10413 and 10426 same sale

[RixStix]

Quite a few error files.

The line items and totals appear correct in the first file that shows a 10413 error
2nd file in the progression shows the sales tax being removed.
3rd file in the progression shows success but sales tax has been removed.
4th file much longer and has the notice regarding PP wacky math.

Total presented for payment on my paypal page shows the invoice total without sales tax.

Click OK for payment on PP website.
Upon transfer back to the ZC confirmation page, big RED banner indicating 10426 error.

I can attach the 4 debug files after I sanitize identifiable information.
