If I have a ddmatch question with several identical answers, this is no longer possible in the new version, because answers can only be used once. From my point of view, this is a mistake.

Reproduce:

1. Create a question with the question type drag-and-drop matching.
2. Choose the same answer for several questions
3. Test the question in the preview or in a quiz and each answer is only available for selection once and not several times.
