What is the SEO plugin are you using?

These instructions came from a firm but I do have the Yoast SEO.

Can you give me more details for further checking?

The above urls are having the same content as

Raven crawlers are considering these to be duplicate content. If possible we need to change the content on individual pages to avoid presenting them as redundant.
