Bootstrap 4 navigation tabs content not showing content on initial page load

On initial page load, the tabs show but the content for that selected tab does not.

If I click the “Link” tab and back to the “Post” tab then it shows up.

<div class="container">
    <div class="card text-center">
        <div class="card-header">
            <ul class="nav nav-tabs card-header-tabs" id="tabs">
                <li class="nav-item">
                    <a class="active nav-link" href="#post" data-toggle="tab">Post</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#link" data-toggle="tab">Link</a>
                </li>
            </ul>
        </div>
        <div class="card-body">
            <div class="tab-content">
                <div class="tab-pane" id="post">post</div>
                <div class="tab-pane" id="link">link</div>
            </div>
        </div>
    </div>
</div>

On page load it looks like this (the div with the tab-pane class hasn’t been displayed):

There are no errors in my console and the bootstrap JS file is loaded. There are some similar questions around but the solutions have not worked for me.

What do I need to add to get the tab pane to display when the page loads?
