Featured Image not showing with Comic Easel and Fluida

I’m having a hard time getting the featured image to show in my comic (as seen in this page). The image used for the featured image is the following: http://morgrog.com/wp-content/uploads/2018/03/Flowa-1.png

The source is as follow:

<main id="main" role="main" class="main">
		
		
			<article id="post-263" class="post-263 comic type-comic status-publish has-post-thumbnail hentry chapters-comics" itemscope itemtype="http://schema.org/Article" itemprop="mainEntity">
				
							

			

			
			
				
	 				
	 				
										
				
			
			
			

		

Fluida’s Feature Image Customization options are as follow:

Featured Image: Enabled
Auto Select Image From Post Content: Enabled
Max Featured IMage Height (in pixels): 0
Featured Image Behaviour: Contained
Featured Image Alignment: Center Top
Featured Images in Header: Disabled

I tried regenerating the thumbnails as well with the “Force Regenerate Thumbnails” plugin.

I’m using the Fluida theme with comic easel v1.14.

I have no clue what is going on 🙁

Thanks!
