Hi @chrisandlisa91 that is correct, the default behaviour is to append the word Category or Tag to the beginning of the page title. The automated process WordPress uses does not connect the content to the pages that you have made manually using your preferred URL structure and title.
However, you can consider adding either the Blog Posts block or the Query Loop block into those pages, and that is a way you can quickly add a dynamic feed of blog posts. Both of these options include the ability to add a filter, so the output is limited to a specific tag or category.
Either block will result in a blog post feed on your page, but they can differ in their appearance and customization details. For the fastest/easiest path, we recommend the Blog posts block, if you want a whole bunch of (possibly too many?) customization options the Query Loop block is a better fit.
We show how you can add both in this webinar:
