One Order Invoices and delivery slip cannot exist at the same time

[VBLED]

It is very strange that one order can only have either invoice or delivery slip, it can not have both document, why the system design like this?????

I can swear I've seen shops with both icons next to each other. Maybe it depends on some conditions or configuration. Maybe the order status for sent orders must also be marked as paid or something like that?

The problem is I have to print the delivery slip firstly, and then I found the button: Gernerate Invoice is missing.

So I have to delete the delivery slip file and then this button come back, and then I can generate invoice.

If I firstly generate the invoice then I can not get the delivery note, this is very bad.

OK,  I found a solution:

Change the file src\PrestaShopBundle\Resources\views\Admin\Sell\Order\Order\Blocks\View\documents.html.twig

Remove the if condition below:

{% if  orderForViewing.documents.documents is empty and orderForViewing.invoiceManagementIsEnabled %}

//keep inside code.

{% endif %}
