Wacka Alpaca's stage mix-up messed me up

[Pepito 21]

Ok well I decided to start making hacks myself instead of just downloading them. So I watched WackaAlpaca's Brawlbox Tutorial - Creating Stages From Elements Of Other Stages

. It started off well and I could do the things he did, but then he messed up . At around 5:42 an annotation comes up that says that he messed up and that I should do what I did on the new animation to the pre-exising one which is changing the Y-translation to 55. I did that to the Final Destination platform and it came out all weird looking. When I keep changing it, either the Big Blue platform becomes invisible, or the Final Destination platform is on top of a visible Big Blue platform. I want to know what the annotation means, am I supposed to change the Y-translation and if so, on what? Plz help.

try following instructions without following that annotation

That was my first try, it ended up making the platform invisible or at least "not there" but the collision was still there.
