[Plugin: WP Featured Content] Bug since latest update

Hello,

I am at a loss with the latest update of WP Featured Content plugin, or maybe since I updated WordPress to 4.5.2.
Since the update, no matter what I do (editing my content via the wysiwyg or html source code, deleting and created featured contents again, shortening the code to display featured contents…), there is no way to implement rich text in the displayed boxes under the icons.

As a result, what should be displayed as justified lists with bold items (the only way to make it “readable” for clients) is displayed as a centered seamless string of characters. I am even contemplating deleting the plugin for good – such a pity !

Many thanks in advance for your help !
