Options Multiple Choice not randomized again

My customer wants this behavior of a MC-question:

On answer OK: That's OK

On answer Not OK:

The student must clicking a button AGAIN and the question is presented again and the options in a new random order.

I did this with a trigger (Jump to slide) on the AGAIN button that jumps to itself. When the AGAIN button is clicked for the first time the question is presented again, but the order of the options is not randomized.

Is there a way to force randomizing?

Ps. In the Form View the option Shuffle is selected
