Hello Marta,
The contents of the content area element in section 8 has a broken code.

You need to check all 4 columns. And then I also found out that you added this html code in X > Theme Options > Header > Miscellaneous > Topbar Content:
<div class="home-header">
<img class="border-img" src="https://pulmonarywellnessonline.com/staging/2553/wp-content/uploads/2018/09/glow-border.png">
<div class="home-header-info groovybg">
<div class="home-logo"><a href="https://pulmonarywellnessonline.com/staging/2553"><img src="https://pulmonarywellnessonline.com/staging/2553/wp-content/uploads/2018/10/ONLINE-ICON-bev-1-e1539549416333.jpg"></a>
</div>
<div class="logo-text">

<div class="online-pr"><img class="online" src="https://pulmonarywellnessonline.com/staging/2553/wp-content/uploads/2018/09/ONLINE-e1547157754315.png"><img class="pr" src="https://pulmonarywellnessonline.com/staging/2553/wp-content/uploads/2019/01/PulmonaryRehab-min.png"></div>

Please be advise that the output of the topbar content is wrapped with a <p> tag. You cannot nest a <div> tag inside a paragraph tag. It will create issues. Please remove your custom code and find an alternative in modifying your topbar content.
Hope this helps. Please let us know how it goes.
