CakePHPで編集フォームが作成されない

Question

前提・実現したいこと

CakePHP3.7.3(PHP7.3.1)で、スケジュールアプリを作っています。
「schedules/edit/13」のようにedit テンプレートへ飛んだ際に、Formに該当するidの情報が表示されず空欄になってしまいます。

公式(https://book.cakephp.org/3.0/ja/views/helpers/form.html)を見ると、
「FormHelper は、追加 または 編集 のフォームを作成するかどうかを自動的に検出するために、 Entity オブジェクトを使用します。 提供されたエンティティーが「新しくない」場合は、 編集 フォームとして作成されます。」とあります。

なぜ編集フォームが作成されていないのかが分かりません。お助けください。

回答ありがとうございます（＿ ＿）
valueSourcesを付けてみたのですが変化なしでした。。
もう少し調査してみたいと思います。

自己解決しました。
<?= $this->AppForm->create($schedule) ?>
