I am getting issues in my form since the last update (Version 1.7.0) this was working properly before.
Basically, if you open the form, you should only see the first radio choice between sofortkauf (instant-buy) and finanzierung (financing).
If you choose instant buy, you should see some fields then, including the ones at the bottom of the form, like comment field, send button etc.
However, if you choose financing, you get send to the 2nd big radio option.
"als pdf-datei runterladen und ausfüllen" download as pdf and fill out manually or "jetzt online ausfüllen" fill out the online form now.
When selecting the pdf option, you should see no more fields except the one html field with the download link to the pdf.
If you select the online form, that's when you get the whole load of fields.
