PayPal order summary problem with product delete

[PrestaShark]

Hi i have weird issue.

 

When i switch the PP module to normal mode (instead of Sandbox) the Delete product button on order summary is missing.

When i disable PP module the buttons are showed.

 

This issue is releated with latest Firefox. Chrome works normal and the button is visible.

And the main thing. When i watch at page source code in Firebug the

<td class="cart_delete">
                    <div>
                
            </div>
</td>

is visible. But in browser "Show page source code"

the

<td class="cart_delete">
                    <div>
                <a rel="nofollow" class="cart_quantity_delete" id="556_7596_0_0" href="http://xxx.pl/pl/koszyk?delete=1&id_product=556&ipa=7596&id_address_delivery=0&token=3468c8ec27e873b28d92d36798420819">Usuń</a>
            </div>
                </td>

is available...

 

Im confused! Any ideas!?

Thanks in advance!

 

PS 1.5.6.2
PP 3.6.6
