generatepress button issue in sticky bar

Hey, GP team
Today, I was adding button in my navbar, found one of the gp post and implemented it’s CSS.

It looks like something this

@media (min-width:769px) {
	.main-navigation .main-nav ul li.aj-nav-tools a {
	background-color: #5d3ce6;
	border-radius: 10%;
  color: #fff;
	line-height: 30px; 
    }

Button looks good but, while I scroll and it get stick on the top of the bar, you can look at page.
Can u help me solve it.
??
