Hi Chris,
Thank you for writing in and sorry that you’re having that issue please update the navigation label you used to this:
<i class="x-icon" data-x-icon-b="" aria-hidden="true"></i>
Replace the 
with your actual icon’s unicode. You can copy icon’s unicode here.
You need to determine what group your icon belongs, because as of Font Awesome version 5 they split icons into multiple fonts group. This can be fixed by changing instances of the data-x-icon
attribute to one of the following:
-
data-x-icon-b
for brand/social icons.
-
data-x-icon-o
for outline icons.
-
data-x-icon-s
for solid icons.
The original attribute data-x-icon
will still work for solid icons as a fallback but we’ve updated everything for consistency.
Release Notes - Pro 2.2, X 6.2, Cornerstone 3.2
Cheers!
