Interaction Hover not working

I f you look in my Div Block Section 4 Bloc 1 (Protocole:Hedera) I have an interaction on mouse hover.

It sets a child at 100% opacity and hover out it sets it back to 0%. Watch it in 1920px and above.

But it doesn’t work how come?

I was testing some few things and realized that my element pop info even without the hover trigger/animation and with 100% opacity don’t appear in preview mode. But I see it in the designer.
