Screen interface

I watched Steve Kaufmann’s “How I Learn Languages From Scratch” video. I think it’s a very good video for beginners. My problem is that I see a completely different screen interface than what is shown in the video. The “Hide Vocabulary” and “Review Sentence” buttons are not visible on my screen. Why could this be? Is it because I don’t have a subscription, or has the software changed since the video was made?

Thank you in advance for your help.
