After upgrade t3 framework plugin to 2.3.0 font awesome icon not working problem

Hi There,
The icon class of font awesome like "fa fa-home" is not working for megamenu all menu items.
(so far it is working for first menu with sub menu but not working for other parent menu or submenu)
I just faced the problem when I upgred the t3-framework plugins from 2.2.1 to 2.3.0.
Any help would be appreciated.
Thanks
