React Scroll Active class is not working? - reactjs

Question

Im using react-scroll and I want to get a border to my Navbar sections when they are in the sections using a className of active. But it works just for the first section.
when I inspect I just see the first li get the active class.
I tried to get them manual class by using react-scroll function activeClass=active and then set a CSS file for the class but it doesnt work either
