Nested repeater problems

[raneri]

Expected Behavior

I'm using a "questions > answers" nested repeater: the question layout contains a second repeater for its questions:
I'm expecting that dragged questions will bring also the answers inside.

Actual Behavior

When I drag a question, it is correctly moved to the new position, but the answers are visually duplicated (if I have answer a, b, c I will get a, b, c, a, b, c -- but when I save they aren't stored duplicated in the database). In addition of this, the index of the "group" of fields of the answers isn't updated, so when I save they are saved to another question. << this is the major problem because it screws up the data

Steps to Reproduce the Problem

This is the layout of the question repeater, that is creating a nested repeater for the answers:

class QuestionRepeater extends Rows
{
    function fields(): array
    {
        return [
            Input::make('id')->hidden(true),
            Input::make('question')
                ->type('text')
                ->size(255)
                ->maxlength(255)
                ->required()
                ->title('Question text'),
            Repeater::make('answers')
                ->title('Answers')
                ->layout(AnswerRepeater::class),
        ];
    }
}
