Review Stars not Displaying on Mobile

I am using the BD Themes ‘Review Card Carousel’ widget to display reviews on the site. Unfortunately, the rating is not displaying on mobile devices. I think it’s an Elementor issue. So far, I have changed the ‘Inline Font Icons’ in Elementor / Settings / Features from Default to Active, from Active to Inactive, and then back to Default. I am out of options. Please help.
