Why doesn't Form Model Binding work when inheriting the Blade template?

Question

Laravel

Laravel 5.4, laravelcollective/html 5.4.8
There is a basic add content page template:

@extends('layouts.master')

@section('content')

<div class="panel-body">
    @if(count($errors))
        @include('common.errors')
    @endif

    {!! Form::model($entry, ['method' => $method, 'class' => 'form-horizontal', 'route' => [$route]]) !!}


    @section('fields')
        @foreach (['title', 'url', 'content', 'meta_tags', 'meta_description', 'is_active'] as $field)
            @include('entries.fields.' . $field)
        @endforeach
    @show


    <div class="form-group">
        <div class="col-sm-offset-3 col-sm-6">
            @section('submit')
                {!! Form::submit('Добавить', ['class' => 'btn btn-default']) !!}
            @show
        </div>
    </div>

    {!! Form::close() !!}
</div>
@endsection

(as you can see, certain form fields are loaded in it via include)
And there is a template for adding articles that extends it, which has its own set of fields:

@extends('entries.create')

@section('title')
    Добавить статью / {{ config('site.site_name') }}
@endsection

@section('fields')
    @foreach ([
    'entries.fields.title',
     'entries.fields.url',
      'articles.fields.description',
       'entries.fields.content',
        'entries.fields.meta_description',
         'entries.fields.is_active',
         'articles.fields.enable_comments',
         'articles.fields.show_on_main',
         'articles.fields.rank',
         ] as $field)
        @include($field)
    @endforeach
@endsection

The point is that when I do not redefine the contents of the form_fields section, the fields are filled with the values ​​from the $entry variable given to the template, but as soon as I redefine the section, prescribing even the same fields, autocomplete stops working.
For example, I have the enable_comments checkbox:

{!! Form::label('enable_comments', 'Включить комментарии', ['class' => 'col-sm-3 control-label']) !!}

     <div class="col-sm-6">
        {!! Form::checkbox('enable_comments', null, null, ['class' => 'checkbox']) !!}
    </div>
</div>

And in the form of adding articles, it always turns out to be unchecked, although $entry>enable_comments === true
If I do not override the section, then it is set according to the provided model instance - checked.
Why such strange behavior, and how to solve this problem?
