Slider (Nestable) configuration error

I don’t understand why the Slider (Nestable), when you switch between looping and fading, doesn’t generate the same effects or interactions.
For example;
In a loop, if we put an enter viewport interaction, it plays every time the slide appears.
But if you set it to fade, only the first slide does it and the others don’t.

I think interactions, on fade, play once at startup since it loads the content and doesn’t save the same settings as loop.

What can be done in this case?

I leave an example for the difference. Same configuration but one with loop and one with fade:
Loop: Inicio – Bihotz Mujer
Fade: Slider fading – Bihotz Mujer
