ACF Custom validation message not showing up

I have two date fields where I want to make sure the end date is always later than the start date.

I added a validation function per ACF's documentation. It does fire, but the custom message does not display next to the field. It only says validation failed on the top.

add_action('acf/validate_save_post', 'my_acf_validate_save_post');

function my_acf_validate_save_post()
{

    $start = $_POST['acf']['field_5fb0e816ea4fc'];
    $start = new DateTime($start);

    $end = $_POST['acf']['field_5fb0e83aea4fd'];
    $end = new DateTime($end);

    // check custom $_POST data
        if ($start  $end) {
            acf_add_validation_error('event_series_end_date', 'End Date should be later than the Start Date');
        }
}

Add this snippet and check according to your needed.

add_action('acf/validate_save_post', 'my_acf_validate_save_post');
    
    function my_acf_validate_save_post()
    {
    
        $start = $_POST['acf']['field_5fb0e816ea4fc'];
        //$start = new DateTime($start);
        $start = strtotime($start);
    
        $end = $_POST['acf']['field_5fb0e83aea4fd'];
        //$end = new DateTime($end);
        $end = strtotime($end);
    
        if( current_user_can('manage_options') ) {
    
            acf_reset_validation_errors();
        
        }
    
        // check custom $_POST data
        if ($start > $end ) {

            acf_add_validation_error($_POST['acf']['field-600e609de8ab8'], 'End Date should be later than the Start Date');

         }else if ($start == $end ) { 
        
            acf_add_validation_error($_POST['acf']['field-600e609de8ab8'], 'End Date should be equal to the Start Date');

    }
    }
