Updated Blog Post But Not Showing The Updated Post In Categories

Hello, Recently I edited a blog post that contained adsense at the top. I removed the adsense from that post and updated it. The problem is that in the category of this post the adsense is still appearing and I cant figure out why that is? If I edited a post and removed something… Shouldn’t that post be updated in the category as well? The homepage everything is displaying properly. But when I click on the category of the post the adsense is still showing up at the top of the post. I hope someone can help me.

Thanks In Advance
Rick
