Hi @SaqlainMughal,

I hope you are well today and thank you for your question.

There is no option to delete specific demo content.

You have to delete all the imported demo content on your website using the below plugin and again reimport correct demo content.

If you don’t want to delete everything then you have to delete pages, posts, categories, custom post types, etc. manually.

Best regards,
