There are several icons that don't show up once I choose them, namely some of the health-related ones like the DNA strand, prescription bottle, pills, etc. I just get a tall rectangle outline instead. Is there a fix? I checked the icon library and Font Awesome 5 is loaded.

    Hi winbytwo ,

    Welcome to the forums!

    There could be another Font Awesome script in your site causing it to show as a rectangle. Perhaps a theme or another plugin. 🤔

    You could try to add this script into your site, making Font Awesome 5 and Font Awesome 4 compatible with each other.

    <link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.13.0/css/v4-shims.css">

    Another reason it could turn into a rectangle is that the font-weight of the icon is being changed.

    If adding the script doesn't work for you, could you perhaps share us a link to your site?
    We would like to take a look and find out what's causing the issue.
