Why is it impossible to edit text in the front-end ACF form?

Question

WordPress

Good afternoon!
Faced a strange case in ACF. Previously, this problem was not observed. I use acf_form() to post stuff through the front end.
Template code:

<?php
  
  acf_form(array(
    'post_id'		=> 'new_post',
    'post_title'	=> false,
    'post_content'	=> false,
    'new_post'		=> array(
      'post_type'		=> 'testimonial',
      'post_status'	=> 'draft'
    ),
    'return'		=> home_url('thank-you'),
    'submit_value'	=> 'Опубликовать'
  ));
  
  ?>

Code in functions.php

// frontend form for adding testimonials 
add_action('acf/save_post', 'testimonial_save_post');

function testimonial_save_post( $post_id ) {
  // bail early if not a testimonial post
  if( get_post_type($post_id) !== 'testimonial' ) {
    
    return;
    
  }
  
  // bail early if editing in admin
  if( is_admin() ) {
    return;
  }
  
  // vars
  $post = get_post( $post_id );
  
  // get custom fields (field group exists for content_form)
  $testimonial_text = get_field('testimonial_text', $post_id);
  $testimonial_name = get_field('testimonial_name', $post_id);
  $testimonial_work = get_field('testimonial_work', $post_id);
  $testimonial_profession = get_field('testimonial_profession', $post_id);
  $testimonial_link = get_field('testimonial_link', $post_id);
  $testimonial_phone = get_field('testimonial_phone', $post_id);
  $testimonial_email = get_field('testimonial_email', $post_id);
  
  
}

The problem is if the value of the post_content field is set to false in the template, then I can't edit the other fields too... I.e. nothing is entered when entering text... And if true, then everything works accordingly... Although t 'post_content' is only responsible for showing / hiding the form in the front. Maybe this is a bug in the ACF Pro plugin?
PS The CPT (function.php) supports 'title' only. (I don't need an editor...)

Answer 1

Maybe it's the version of the plugin? The documentation for it, depending on the version, provides different codes.
