Post Carousel All Posts Showing

I have my carousel set to only show posts from the ‘work’ category. This was working before, but not now. The images show up in the carousel correctly (omitting the ‘blog’ posts), however when you click through the individual posts, they all show up? I only want the ‘work’ posts to be available here. Likewise, ‘blog’ posts to be available when some scrolls through the posts only through the ‘blog’ section on the home page. Can you help me figure out why this changed and return it to operating the way I preferred it?
