That’s the funny thing, it doesn’t happen with “all” themes (including the WordPress default) and when I remove the page nav syntax that’s currently there just to see what will happen it still displays it. Even after copying the same next_posts_link and previouss_posts_link syntax from the default theme still gave me that issue.
Edit: After digging a bit deeper I found out what the issue was, there was another index like page (home.php) that had the same information, updated it in there and it resolved the issue, thank you!
