Иерархия сертификатов PKI

Я следую за https://jamielinux.com/docs/openssl-certificate-authority/index.html, и после создания корневого и промежуточного кода цепочки файл имеет иерархию, как и другие.

Вот пример ожидаемой иерархии:

• Корень создания
• Промежуточный ЦС создан и подписан корневым ЦС
• Сертификат домена создан и подписан промежуточным звеном.

Создать https://jamielinux.com/docs/openssl-certificate-authority/create-the-intermediate-pair.html#create-the-certificate-chain-file

Но после импорта ca-chain.cert.pemчерез Firefox, которые содержат промежуточный и root (именно этот порядок). Просто импортируйте промежуточное звено.

После импорта в браузер веб-сайт работает хорошо, но в иерархии нет корневой буквы. просто промежуточный, а затем сертификация сайта.

Даже после импорта root ca сертификат не имеет иерархии, как я ожидал. Что я пропустил?
