How to get rid of "blog" twice in breadcrumbs without affecting other categories

Hi,

I have set up a custom permalink structure in WP using /%category%/%postname%/

I made a parent page called “success stories” and applied the portfolio grid element.
When I view the pages from the success stories page, the breadcrumb trail is: http://www.website.com/success-stories/post-name

I also made a parent page called “newsroom” and applied the blog posts element and chose the category “newsroom” to show posts.
Breadcrumb trail: http://www.website.com/newsroom/post-name

Then I made another parent page called “blog” and applied the blog posts element and chose the category “blog” to show blog posts.
Breadcrumb trail: http://www.website.com/blog/blog/post-name

I can see where the issue is lying here now… The parent page “blog” should be something else to prevent duplication of “blog”.
If I rename the parent page to “our-blog”, the trail would say: http://www.website.com/our-blog/blog/post-name

Is this a best practice? When and where should we use “blog”? On the parent page or in the categories?

Thank you.
