URIは変わっていないのに別のページが出力されてしまう

###前提・実現したいこと
目的のrouting設定にしたい

###発生している問題・エラーメッセージ
rails で簡単な入力フォームと結果表示のページを作成中ですが
http://XXX.XXX.XXX.XXX/requirements/list
にアクセスを試みた際に、なぜかrouteやControllerで設定していないはずの
http://XXX.XXX.XXX.XXX/requirements/show の画面が出力されてしまいます。
(ブラウザ上のURLは http://XXX.XXX.XXX.XXX/requirements/list のまま）
なぜそうなってしまうのかわかる方いらっしゃいましたらご教授いただけますでしょうか。。。

Controller名：Requirements(show, index, list, new, create)
Model名：Requirement
(db:migrate済み　実際にDB上に値が保存されるところまでを確認しています)
