We reworked the schema to be easier to parse/handle and to streamline used terms. There is an option "use new export format" which allows to toggle between the two formats in case you still have processing based on the old format. The new format is already the default for new customers and support for the previous format will be removed at some point.
Depending on this toggle, you should get the corresponding format in both places, i.e. the "click here to download sample" and the actually exported documents.
