Drag and Drop Question - Return Incorrect Answers back to start

hi everybody! I am struggling with the same question: I need to reset only incorrect answers to the initial state AFTER a learner clicks submit button in drag and drop section. I ticked:

- drag Items Options - return item to start point if dropped outside a correct drop target

- Feedback - delay item drop states until interaction is submitted.

For some reason items still are returning back stray away if I drop them not to the correct box.

If anybody could help, please let me know!

Thanks,

Yulia
