Article Title Has Extra Word “Next” and “Previous” in Title

In desktop search results, my article title is coming up with the word “Next” in front of it. Sometimes it comes up with “Previous.” Someone has pointed out that there are lines of code that have the title tag other than the article header, but I don’t know how to address that or why it is happening. At the bottom of the blog post, there is the opportunity to click either “Next” or “Previous” along with the next or previous blog post, so clearly this is the issue, but I don’t know how to delete that. Someone also suggested it is a plugin, but no idea which one it is. I asked Google to reindex, and now it is coming up “Previous” and article title.
