Hi @ssheward,
We’re rolling out an update now that will roll things back to Font Awesome v4 with the ability to force load Font Awesome 5 through an included filter:
add_filter( 'wpcw_social_icons_fontawesome_5 ', '__return_true' );
Since Font Awesome 5 is not widely adopted just yet, and a lot of themes and plugins are still running Font Awesome 4.7.0, we’ve decided to default to a locally bundled copy of Font Awesome v4 to work around any conflicts, with the option to load Font Awesome v5.
This should fix the issue that you are facing with that icon converting to an SVG icon. The update should be available on www.remarpro.com shortly. Once you update, feel free to post back here and let us know if the issue is resolved on your end.
