No input with nested MultipleInput after remove

[bscheshirwork]

For nested MultipleInput I not have a any data in $_POST for this field in case delete all rows. For 1st level I can see empty string (also is not good, but it exist).

I expect same behavior for 1st and 2st level of MultipleInput

Post an example of the code, please.

    <?= $form->field($model, 'nestedObjects')->widget(MultipleInput::class, [
        'rendererClass' => \unclead\multipleinput\renderers\ListRenderer::class,
        'max' => 6,
        'min' => 1,
        'allowEmptyList' => false,
        'enableGuessTitle' => true,
        'addButtonPosition' => MultipleInput::POS_HEADER, // show add button in the header
        'enableError' => true,
        'columns' => [
            [
                'name' => 'nested1', // attribute
                'title' => Yii::t('object', 'Nested1'),
                'type' => MultipleInput::class,
                'options' => [
                    'max' => 12,
                    'min' => 0,
                    'allowEmptyList' => true,
