Multi step slug - category

**EDIT-resolved ** ok, figured out that I have to separate different categories in to different collections now it works

Hello I wanted to have my blog cms divided by categories

  1. Did it this way - every category has its own blog Sub-page and -single page

Using filtering in my cms by category

And everything works fine on the site, Finally looks like this
https:// naprawimyfirme.pl/blog/category/single-blog

Problem is that in the site map blogs are not categorized(sitemap put them in one- wrong category)?

My site is https://naprawimyfirme.pl/

Will this work properly or this canno be tone this way and have to be just blog/single-blog

Thanks for help
