I looked for an answer on the topic but can’t find any.

I have TranslatePress installed in my WordPress. I used to have multiple languages translation for the website; I wanted to keep only two languages so I removed the other ones via TranslatePress settings. I realized that my website still has pages like http://www.mywebsite/de or http://www.mywebsite/subdomain/es.
This is giving me many issues like SEO Title duplicate and Meta description duplicate.

How can I remove these pages? I cannot find any option anywhere.

Thank you

Best
