Hi,

In the next update can you change the permalink for blog_category to blog-category because it affects Google SEO. 

Using underscores in your URL makes it hard for search engines to determine your site's relevance to a search. Google sees hyphens as word separators while underscores are ignored. So the search engine sees https://www.example.com/blog_category/example/ as all one word. Use hyphens in  URLs instead: https://www.example.com/blog-category/example/
