Missed one in Pottermore

If you have been following Harry Potter for years then you must be knowing of Pottermore. It is the website focusing on unknown parts in whole Harry Potter series and re-tell it in interesting way.
I have signed up for this website like years ago, but just started logging in again yesterday LOL
Just when Harry Potter series were about to end, potterheads were so hyped about Pottermore that was going to be released at that time, and it was damn difficult to sign up since you have to wait in line like two weeks LOL

I started reading Harry Potter when I was only like twelve years old, so when I wrote this entry, the time have passed more than ten years from that time. I have been falling in love with this whole story and the characters. I really miss the time and excitement when I was waiting for new releasing of the books and movies. I have so many Harry Potter merchandises that I have been keeping for more than ten years along with the books. Though unfortunately I can't take all of them with me when I was moving to new house and later to another city. In result, I lost my Fantastic Beasts and Where To Find Them, and Quidditch Through The Ages. I was so mad that I cried when I couldn't find them LOL.

Let's say that I know very well some details in Harry Potter series. So when I opened Pottermore, I found interesting parts in the picture.

By the way, do you notice what's wrong from the picture above?

If you have read the novel and watched the first movie, you might notice it.

Yes, it's the cake LOL.
But wait... it's NOT completely wrong in my opinion.

So what do you think, guys?
