Hide/Show Animation just wont work

Hey there!

I really need some help on this animations issue - just couldn’t figure out what I did wrong.

Here is my site Read-Only: Webflow - RW9

Go down to the very last black section with text (or in the Nav above ‘L’information complet’). I have a couple of Headlines and some text columns. What I want is for all of them to just show the Headline as initial state, and when I click on the headline, the text column below appears. It should be an easy show on 1st click / hide on 2nd click animation.

For some reason, it works totally fine with the first few, but I’ve done around 15 others below, deleted and tried again, because it would just not hide the text column as initial state (although I did state that in the animation). See the last two headlines as example.

Is this a bug or am I doing something completely wrong?

Working on a Macbook pro & tried it with both Opera and Chrome Browser.

Any help is greatly appreciated!
H.
