Hide blank topic thumbnails

I am trying to display a custom block showing 3 new topics on my homepage that uses SquareSpace.

It displays, but I cannot figure out for the life of me how to hide the blank thumbnails.

Anyone have any suggestions?

You can see it here: https://www.breatheheavy.com/

What I want (shows correctly when using the custom block in my community - example):

What is displaying (shows the thumbnails on my squarespace site):

Any help is greatly appreciated!

This is the custom block's template code:

{{if !empty( $topics ) }}
	<header class='ipsWidget__header'>
		<h3>{$title}</h3>
		{{if $isCarousel}}
			{{$carouselID = 'widget-topic-feed_' . mt_rand();}}
			{template="carouselNavigation" group="global" app="core" params="$carouselID"}
		{{endif}}
	</header>
	<div class='ipsWidget__content'>
		<i-data>
			<ul class="ipsData ipsData--{$layout} {{if $isCarousel}}ipsData--carousel{{endif}} ipsData--topic-feed-widget" {{if $isCarousel}}id='{$carouselID}' tabindex="0"{{endif}}>
				{{foreach $topics as $topic}}
					{template="topicFeedRow" group="widgets" app="forums" location="front" params="$topic, $layout"}
				{{endforeach}}
			</ul>
		</i-data>
	</div>
{{endif}}

PS - worth mentioning: I use this application: Topic Thumbnail. Not sure if it's because of that or not. I disabled it and the gray thumbnails still showed so idk ¯\_(ツ)_/¯
