My avatar has a difference appearance than my career caf

Got it... You imported your one CAF/Avatar to the Carrer Mode.

In Carreer Mode you can edit hair, beard etc but it won't change on your avatar/Caf in the main menu or in-game. 

Basically they splitted his one character into two seperate fighters when starting a career. 

It's definitly weird and shows that carreer mode really has no benefits. Your "legend" won't be the same as the CAF you created and worst of all, you can not use your CarreerFighter Offline/Online or as an Avatar.
