Help! Cant see my debuff aplied on the target!

Hey everyone, i recently bought a warr through the trade system and it all went good, however once i got in game i noticed that i cant see the debuffs i apply on the target such as "Rend" or "Hamstring" etc, i can see the dmg being done by the "Rend" however i cannot see it on the target,tried deleting the cache,reloading ui,reseting the settings pretty much everything ;/ anyone has any idea how to fix it, here's a screenshot to give you an idea of whats going on
