How to fix an error in a widget?

Question

Yii

I installed the yii2-multiple-input widget, but when adding blocks, I get the error Setting unknown property: unclead\multipleinput\MultipleInputColumn::default, that is, I also connected this class additionally, but I still didn’t understand what the problem
was Here is the code

<?php $form = ActiveForm::begin([
    	'enableAjaxValidation'		=> true,
    	'enableClientValidation' 	=> false,
    	'validateOnChange' 			=> false,
    	'validateOnSubmit'			=> true,
    	'validateOnBlur' 			=> false,
    ]); ?>
    <div id="customForm">

    <?= $form->field($custom, 'custom')->widget(MultipleInput::className(), [
    	'max' => 6,
    	'columns' => [
    		[
    			'name' => 'tovar',
    			'type' => 'textInput',
    			'title' => 'Товар',
    			'default' => 1,
    		],
    		[
    			'name' => 'number',
    			'type' => 'textInput',
    			'title' => 'Кол-во',
    			'options' => ['min' => 0]
    		]
    	],
    ]) ?>

'default' => 1,take away. The error clearly says that there is no such property
