Archive and category now showing all topics..

Please help me, my archive and categories are not showing total posts. If I set “3” for the number of posts in the homepage, the categories and Archive also shows “3” posts and there is no link or links for other older posts..

Here are example of pages.
For category- https://www.myseoblog.net/category/seo/

For archive – https://www.myseoblog.net/2007/11/

Other posts are not showing..
Thanks
