Header not on top

I have a website built with WPBakery (not created by me but I need to do some changes on it) and the current header is a smart section sticky, I need to set it as a normal header (which don’t stay on top when I scroll down) but every time I try to set it as header, it goes below my footer.

I’m pretty new to wordpress so it’s probably a basic problem but I really don’t understand why this work like this.
