How to change the URLs of the posts or articles

Hello,

I purchased this theme, but how to change the URLs of the posts/articles? All articles have this /docs/docly-documentation/elements/ in the links.
When I try to edit, it does not let me change. I do not want the word ‘docs’ or ‘docly-documentation’ in my links. please tell, how do I fix that. thanks. Rerum cubilia, ultricies cillum, dignissim dignissimos, omnis magnis, commodi donec maecenas incididunt metus wisi

Thanks
