The Java Series Inquiry

So I bought the ‘The Ultimate Java Mastery Series’ and I noticed something that I found strange. For some context, this course includes three parts. When I went to start ‘Ultimate Java Part 1: Fundamentals’ in the ‘Getting Started’ section, video 6 titled ‘Course Structure’. On the 10 second mark, it shows the image attached below.

I got confused when I saw there are 4 parts in the image as I only got three parts. Am i getting it wrong or what?
