The day and month are inverted in PDF invoice

[Denys06]

Hello,

 

Today I discovered a problem on my Prestashop 1.5.6.2.

 

Some of my invoices in court for delivery or not delivered have the day and month reversed.

 

I have defined in my design files .tpl:

 

{$ date | date_format: "% d /% m /% Y '| escape:' htmlall ':' UTF-8 '}

 

But the invoice show me : % m /"% d /% Y

 

What is really bizard is that some invoices show the date in the correct format and others do not, I do not understand why some invoices have reversed time.

 

Do you have an idea please?
