No details showing on tracking page

Hello,
I am trying to set up the on-site tracking page, but I can’t get tracking info to display on it.
Even if I add the carrier (DB Schenker) tracking number to the order, all I can get on the page is :

PENDING

But this order is already delivered ; you can check with this DB Schenker tracking number : FRMVK851118948

How can I solve this ?

Thanks in advance for your answer.
Best regards,
Greg
