Do not link to other categories

Hello, I know how to add a post to a category, but when i click on (or create a link to the post), and then scroll through the posts, I only want them to go through that particular category and not all the other posts from all other categories. (attached image shows Fort George & Bend Brewing scroll at bottom, but both are in different categories) I want to avoid this. Is there a way that I can limit posts not displaying links to other categories please?

here is an image:
