I use the autoformat on save function. That works really good. But when there is IF and ELSE in mixed html/ php code it pushes the code between IF/ELSE a tab to the right on every save/ format.
Why is that?

It ends up with the code being pushed way out right.

                                    <td align="right">
                                        <?php echo Text::_('COM_REDSHOP_BILLING_AS_SENDER'); ?>:
                                    </td>
                                    <?php if ($shipping->billing_as_sender == 0): ?>
                                                <td>
                                                    <?php echo Redshop::getConfig()->get('SHOP_NAME'); ?>
                                                </td>
                                    <?php else: ?>
                                                <td>
                                                    <?php echo Text::_('COM_REDSHOP_BILLING_AS_SENDER_SITE_CUSTOMER'); ?>
                                                </td>
                                    <?php endif; ?>

So it means

                                    <?php echo Text::_('COM_REDSHOP_BILLING_AS_SENDER'); ?>:

is correct formattet but the rest is pushed right every time i save.
