Pagination listed as self-referencing but showing up as blocked?

Running a technical audit on site arch and I think we might have self-referring pagination incorrectly set up.

Subsequent pages after the initial blog page this-site-dot.com/blog/ all should go to /blog/ URL. However pagination blogs are listed as blocked based on this Screaming Frog visualisation?

I say this along side as we've also noticed that our older blog posts haven't been indexed as much. 

Subsequent blog pages (i.e. /blog/page/3/ .../blog/page/14/) are structured as follows with rel=canonical added 

<link rel="canonical" href="https://this-site-dot.com/ru/blog/" class="yoast-seo-meta-tag" />

https://this-site-dot.com/ru/blog/page/3/?et_blog —> https://this-site-dot.com/ru/blog/

Robots isn't blocking any pages as well per .txt review. 

Is this a non-issue?
