MB Term Required Validation Not Working

Hi,

The required validation for the fields in add new terms not working, it works only in the edit term page, but when trying to add term the validation not working.

 $meta_boxes[] = array(
        'title'      => 'Banner',
        'taxonomies' => 'news-categories',
        'fields' => array(
            array(
                'name'  => 'Title',
                'id'    => 'banner_title',
                'type'  => 'text',
                'required'  => 1,
            ),
            array(
    
                'name'  => 'Description',
                'id'    => 'banner_description',
                'type'  => 'textarea',
                'desc' => 'Maximum number of characters is 45',
            ),
            array(
                'name'  => 'Body',
                'id'    => 'banner_body',
                'type'  => 'textarea',
                'desc' => 'Maximum number of characters is 150',
            ),
            array(
                'name'  => 'Image',
                'id'    => 'banner_image',
                'type' => 'image_advanced',
                'max_file_uploads' => 1,
                'required'  => 1,
                'desc' => '(250 x 250)',
            ),
    
        ),
        'validation' => array(
            'rules'  => array(
                'banner_image' => array(
                    'required'  => 1,
                ),
                // Rules for other fields
            ),
        )
    );

Can you help me to fix this?
Thank you,
