Why my carousel doesn’t get down under my sticky navbar?

I decided to add a carousel to my website in the second section (in the middle of the page after the hero), then I try to add a sticky navbar and it’s work correctly except for the carousel shown above the navbar.

here is the code I used for the carousel (I used Bootstrap 5).

<section class="bg-dark text-dark text-center text-sm-start MyContent">
    <div class="bg-light">
        <div class="container" >
            <div class="d-sm-flex align-items-center justify-content-center">

                <!-- carousel -->

                <div class="carousel slide Mycarousel" id="demo" data-bs-ride="carousel">

                    <div class="carousel-indicators">
                        <button type="button" data-bs-target="#demo" data-bs-slide-to="0" class="active" aria-current="true" aria-label="Slide 1"></button>

                        <button type="button" data-bs-target="#demo" data-bs-slide-to="1" aria-label="Slide 2"></button>

                        <button type="button" data-bs-target="#demo" data-bs-slide-to="2" aria-label="Slide 3"></button>

                        <button type="button" data-bs-target="#demo" data-bs-slide-to="3" aria-label="Slide 4"></button>

                        <button type="button" data-bs-target="#demo" data-bs-slide-to="4" aria-label="Slide 5"></button>
                    </div>

                    <div class="carousel-inner">
                        <div class="carousel-item active">
                          <img src="/images/very.jpg" class="d-block width1" alt="...">
                          <div class="carousel-caption d-none d-sm-block">

                        </div>

                        <div class="carousel-item">

        </div>
    </div>
</section>

this is the Javascript code I used for my sticky navbar.

window.onscroll = function() {myFunction()};

var navbar = document.getElementById("navbar");
var sticky = navbar.offsetTop;

function myFunction() {
  if (window.pageYOffset >= sticky) {
    navbar.classList.add("sticky")
  } else {
    navbar.classList.remove("sticky");
  }
}
