Can’t create label – absenderreferenz

Hi there

Since the last update the system is asking for an “absenderreferenz”.

This is new to us and we can’t find a solution for that. Each time we try to create a label (manually) the system gives us an error “could not create label – Unbekannte absenderreferenz”.

So we headed over to woocommerce > Settings > shipping > DHL and inserted “{order_id}” into the empty box “shipper reference”. But this doesn’t seem to work as in the payment reference.

As we couldn’t send parcels in days, please help us out DHL!

Thank you in advance.
All the best
