Frontend form populating with page (not post)

I have a long form to edit my research custom post type. This is the beginning:

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

function your_prefix_function_name( $meta_boxes ) {

    $prefix = '';

    $meta_boxes[] = [
        'title'      => __( 'Academic: Research Summary', 'your-text-domain' ),
        'id'         => 'academic-research-summary',

        'tabs'       => [
            'page_1'  => [
                'label' => 'One / Multiple',

            'page_4'  => [

                'tab'  => 'page_2',
            ],

But I have the issue that it is editing the page it is on and not the custom post type. The title field populates with the page title. This is my shortcode [mb_frontend_form id="academic-research-summary" edit="true" post_type="research" confirmation="Saved" post_id="current"]

why is it not working with my custom post type?
