SEM Rush – duplicate meta descriptions

I use SEO by Yoast and also subscribe to SEM Rush for assistance to improve my ranking, keywords, etc. My website features approximately 100 blog posts. Each week my SEM Rush report comes back saying I have 200+ pages with duplicate meta descriptions.

The majority of these pages are my blog post index listing pages – eg:
https://www.mywebsite.com/author/blogs/page/1/
https://www.mywebsite.com/author/blogs/page/2/
https://www.mywebsite.com/author/blogs/page/3/, etc.

Another batch of these errors relates to the blog post category:
https://www.mywebsite.com/category/blog-category/page/1/
https://www.mywebsite.com/category/blog-category/page/2/
https://www.mywebsite.com/category/blog-category/page/3/

Is there a way to change the meta description for each of the blog post index pages? Will Google be penalising me for this?

Thanks for your help. I appreciate your time.
