LifeCycle Designer - malfunction after Reader Extended PDF

Dear all

please see the attached Files (XML as the original how it is direct from LifeCycle Designer – and reader.pdf as it is after saving the PDF as a Reader Extended PDF).

As you see, the items that can be added and Removed (Products with dropdown lists and textboxes), are shown 5 times after saving with the extensions. but initially it should be shown only once.
Also when manually removing the 4 other "products" and save as new filled in file, the boxes appear again when reopening.

WHY? i cant figure it out and like to avoid to build the entire form again.

TIA
Andrea
