Bootstrap 4 full width carousel showing other slides - css

Question

I'm using Bootstrap 4 carousel and trying to make it full width. And at first glance, it looks like full width, but then when you take a look at it at larger screens, the rest of the sliders after the first one show up as well. Just try zooming out the window.
How can I fix this?
Here's my code:
.first-slide {
background: url("https://image.ibb.co/kvhXGH/jetty_1373173_1920.jpg");
}
.carousel-item {
height: 800px;
width: 100%;
}

Have you considered checking the markup on Bootstrap's website?
.carousel-item img {
max-height: 100vh;
object-fit: cover;
}
<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-beta.2/css/bootstrap.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
<div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
<div class="carousel-inner">
<div class="carousel-item active">
<img class="d-block w-100" src="https://image.ibb.co/kvhXGH/jetty_1373173_1920.jpg" alt="First slide">
<div class="carousel-caption d-none d-md-block">
<h5>Title</h5>
<p>Text goes here</p>
</div>
</div>
<div class="carousel-item">
<img class="d-block w-100" src="https://image.ibb.co/kvhXGH/jetty_1373173_1920.jpg" alt="Second slide">
<div class="carousel-caption d-none d-md-block">

<div class="carousel-item">
