Advanced custom fields html formatting stripped

Hi,
Hey, where you able to successfully Add ACF custom fields to an Event in front end.
I know this is an old post.But just incase if you could help with my situation.

I added a custom field to my event-editor.php.Got the ACF fields to appear but the data is not getting saved in my backend.The ACF field has data in there even when I create a new event.Any help would be really appreciated.
this is what I did.
in my functions.php i added the following code

add_action( 'init', 'acf_head_add' );

function acf_head_add(){
    acf_form_head();
}

In my event-editor.php I added the following code where i need my ACF field to appear

<?php acf_form(array(
   'post_id'	=> $post_id,
   'field_groups' => array(1463),
   'form' => false,
   'return' => '' ,
)); ?>

Thanks
Diona
