Issue with updating repeater sub-field (image field)

Hi gues!

I need some help with updating repeater field (actually image sub-field) from front-end.

Use ACF v. 5.9.2.

My code

$user_id = get_current_user_id();

$orders = get_field('order_and_screenshot', 'user_' . $user_id);

foreach ($orders as $order) {

    $order_screenshot = $order['order_screenshot'];

    if (  !$order_screenshot ) {

         acf_form(array(
            'post_id' => 'user_' . $user_id,
            'fields' => array(
                'order_screenshot' //sub-field name
	    ),
        ));

    }
}

I select an image and submit the form. After submitting the post image is not updated on the back-end (user page). But I see this image on the front-end.
Checking the database. And find these fields in wp_usermeta:

order_and_screenshot_0_order_screenshot
order_and_screenshot_1_order_screenshot
order_and_screenshot_2_order_screenshot
order_screenshot //I can’t understand why. The value of this field contains the correct image id, which is what I need. But I don’t created it (in repeater field only, not separate).

How can I properly update this image field in a loop?

I would appreciate your help! Thanks you!
