Hi,
the issue is because when we put last update for this theme all names for this font icons is with old prefix (icon-), but now it is icomoon-. For example, so far for the first icon you have icon-mail3, now is icomoon-mail3. Just be sure that in Settings/The Creator – second tab “Font Icons” you have check “Enable Icomoon Icons” and this would work fine, we changed the old names of icons :)
Cheers
