The tax for shipping and handling is displayed twice on my PDF invoices

Question

We have a issue with our invoice grand total where the shipping tax is added twice.

Answer 1

This is Magento core bug, here is source of fix https://github.com/firegento/firegento-pdf/commit/0f96532a870a32ce1cea2730f6afbe14e1863407

You need to overwrite app/code/core/Mage/Sales/Model/Order/Pdf/Abstract.php can change line

foreach ($total->getTotalsForDisplay() as $totalData) {

to

$uniqueTotalsForDisplay = array_map('unserialize', array_unique(array_map('serialize', $total->getTotalsForDisplay())));
                 foreach ($uniqueTotalsForDisplay as $totalData) {

This is not best solution but works good as hotfix, not edit core directly!
