<pre lang="CSS">
.menu a:hover {
  color: #fff;
  background: #000;
  border-radius: 3px;
  transition: 0.4s; }

.menu a {
  font-size: 12px;
  font-family: montserrat;
  color: #afb0b1;
  text-align: center;
  padding: 16px 19px;
  line-height: 12px;
  margin: 0px -5px; }

.nav-pills .nav-link.active, .nav-pills .show > .nav-link {
  background-color: #f3f6f9;
  color: #000; }

.dropdown-menu {
  background-color: #000;
  padding: 0px;
  border: 0;
  margin: 1px 0px 0px 0px; }

.dropdown-menu a {
  text-align: left;
  padding: 12.5px 69px 12.5px 22px;
  line-height: 12px;
  margin: 0; }

.dropdown-menu .aboutUs {
  text-align: left;
  padding: 20px 69px 12.5px 22px;
  line-height: 12px; }

.dropdown-menu .FAQ {
  text-align: left;
  padding: 12.5px 69px 20px 22px;
  line-height: 12px; }

a.nav-link.dropdown-toggle:focus {
  color: #fff;
  background: #000;
  border-radius: 3px; }

This script give the issue

$( ".dropdown-menu" ).css('margin-top',0);
$( ".dropdown" )
  .mouseover(function() {
    $( this ).addClass('show').attr('aria-expanded',"true");
    $( this ).find('.dropdown-menu').addClass('show');
  })
  .mouseout(function() {
    $( this ).removeClass('show').attr('aria-expanded',"false");
    $( this ).find('.dropdown-menu').removeClass('show');
  });

What I have tried:

I tried remove css style to understand why, but it didn't help.

Based on the demo provided, look like the issue is the dropdown menu appears all the way to the left. Look like the page is using bootstrap and the left identation is drive by this style.

CSS

.dropdown-menu-right {
    right: 0;
    left: auto;
}

I would suggest to remove the style dropdown-menu-right from this line

<div class="dropdown-menu dropdown-menu-right">

to

<div class="dropdown-menu">

By the way, the html markup is missing a close tag for <ul>
