I don’t know why but the megamenu in sticky stoped working after updating to bricks 1.9
You can test it here: https://bloommarbella.es/
It’s weird because it works when I call the chrome inspector.
I have other header template for single product with the same configuration and it works perfectly:

I’ve also tried applying the CSS selector and didn’t work
I’m using bricks extras header
