What happened to the “how to comb your moustache” easter egg

So I started to replay doom eternal yesterday, And when I got the chance I immediately went to the bookshelf in the doom slayers collection room. And I swear to God “how to comb your moustache” is no longer there. My question is: why did they change it or is it just the ps5 version of the game

P.s: the first image was a screenshot I found online of the original book, and the second one is a screenshot of the same book I just took today.
