From the release of our theme, we were supported Font Awesome icon font version 4.7 that is used by WPBakery. But since the latest plugin update, WPBakery is moved to the newer version – Font Awesome 5 and we were forced to switch to the newer version.
Font Awesome 5 has constantly updated and contain much more icons but, unfortunately, some of newer icons may be visually different from 4.7 version. Also, all CSS custom code related to the icons needs to be updated because “font-family” parameter has been changed from “fontawesome” to “Font Awesome 5 Free” (for regular icons) and “fontawesome” to “Font Awesome 5 Brands” (for social and company icons).
Here is an example of the custom CSS for Font Awesome 5

body .woodmart-my-account-links div a:before {
  font-family:'Font Awesome 5 Free' !important;
  font-weight: 900;
}

and this one is for the products count

.woocommerce-result-count {
  display: none;
}
