Blank page for cloneable field inside a group

Hi.
Seem like a clonable field inside a Group leads to blank page issue next time editing a post.

Fields structure (Using Custom Table):
yo_benefit_en (group)
--intro (textarea)
--physical_en (textarea, cloneable)

There is no issue editing the intro field. But any time I edit physical_en field > save the post > refresh > it leads to blank page.

If I turn off the cloneable option and create a new post, the issue isn't presented, but the old post still gets the blank page.
If the field value of the old post is removed from the database, the issue is also gone.
So I think there is some issue with saving cloneable field inside a group to the database.

I attached the generated code below.

<?php
add_filter( 'rwmb_meta_boxes', 'your_prefix_function_name' );

function your_prefix_function_name( $meta_boxes ) {
    $prefix = '';

    $meta_boxes[] = [
        'title'        => __( 'Yoga Pose - Extra', 'your-text-domain' ),
        'id'           => 'yoga-pose-extra',
        'post_types'   => ['post_yoga_pose'],
        'closed'       => false,
        'storage_type' => 'custom_table',
        'table'        => 'h0td0nut_mb_yoga_poses_extra',

            [
                'name'              => __( 'Benefits', 'your-text-domain' ),
                'id'                => $prefix . 'yo_benefit_en',
                'type'              => 'group',
