Image in blog header has disappeared

Hey GP,

I use an element class to feature a custom field in the headers of my blog posts. The element class is triggered by a specific tag that represents the writer / medical reviewer of the article. The headers are split into three columns: (1) text that covers what the article is about, (2) "Written and reviewed by:" text, and (3) an image of the reviewer.

At some point over the last 10 days, the images of our reviewers (i.e., the third column of our headers) have disappeared. I can't figure out if this happened before or after my most recent round of GP theme updates and plugin updates.

Any thoughts on what might be going on?

For reference, here's the element HTML for one of the headers (same as the listed link):

<h1 class='header' align='center'>{{post_title}}</h1>
<div class="header-section">
    <div class="header-section-1">
{{custom_field.overview}}
	</div>

    <div class="header-section-2">
        <p align='right'>Written and reviewed by:
								<br>
					<a href='https://perfecthairhealth.com/team/'>Rob English, Medical Editor</a></p>
					</div>
		<div class="header-section-3">
					       <img src='https://perfecthairhealth.com/wp-content/uploads/2019/07/RE-header-100x100.png'>
			</div>
	</div>

In any case, I'm a huge fan of GP and can't thank your team enough for all of the support you've provided over the past year.
