If payed with apple, house number is missing

we encountered the problem, that appears at least with apple pay.

The costumer has prefilled his Apple Pay address with correct details.

during checkout the uses this prefilled details.
but receipt address contains the housenumber, delivery address does not.

we’ve checked with customer if housenumber is given. Somehow at the delivery-address the housenumber is lost or cut.

we have custom-code that prevents entering the street field without a number, so the data must be taken from Apple Pay during checkout
