Animation not going through

Hi!

The problem is on this page here:
https://sono-arte.webflow.io/galerie-so-copy

the animation (small part becomes big, big part becomes small, content appears and disappears) behaves correctly if I click in the left or right part of the lower main section. I have attached exactly the same animations to the header section, but it doesn’t go through with it, only parts of it happen.

Is it a bug? Or is there a logical solution to this?

In the meantime I solved this by redoing the header animation from scratch. Seems like the same animation doesn’t work the same if applied to another trigger.
