Tab change animation does not run


Hello,
I am trying to add some life to a project website with some interactions and animations. Currently I want to use the tab change trigger to animate in the text of the current tab. I started with just the header but the animation does not work when I toggle preview. When I am making the animation and preview it there it works as intended but when I publish or toggle the site preview the tab change animation does not fire when I navigate between tabs.

If you toggle between preview and designer the initial tab animation will load just that once but not when switching between tabs.

Can anyone see what I am doing wrong?

Thank you!
