Doesn't print "supplement" part of street address

[YiffyToys]

An input address line for a US address
"%housenb% %street%, Apt #%apt%
gets broken up into

Street Name: %street%
Street Number: %housenb%
Supplement: "Apt #%apt%"

But in the resulting label the supplement=apartment number is not printed as part of the label.
Causing an already expensive 36.13€ parcel to be returned with an additional 20€ return fee.

@YiffyToys Do you see the supplement-part (addressAddition) actually getting transmitted to DHL in the SOAP request?

If you see the apartment data in the request, I suspect this is (once again) the problem we already had in the past, meaning DHL decides based on the destination country if the supplement gets printed on the label or not.

A solution (or workaround, if you will) to prevent this problem altogether is explained in the above FAQ article (also available in English).

Seems to be that known issue.
