Page bulk loading (entirely) - page load trigger not starting

Hey there,

I am not sure but something I did wrong.
I originally implemented a preloader like this:

with configuration like this

When clicking on preview now, it also is doing the action which it should.
However, what is not happening anymore is, that it starts when the site is loading.
I don’t know what i changed specifically cause it was working once but now the entire page is first shown after everything has loaded. That’s also why the interaction shown above is not kicking in anymore. At the time I see see page it is already “over”.

Can you help on what I did wrong here?

Kind regards,
