Bug Elemental Shaman,2 pieces Tier 6 set

Hello, sorry if i dont respect the template 100% ,but here is the issue. For elemental shaman the two set consists of 35spd,1%+ crit and 15 mp5 if four different totems are put down at the same time. Which i did : tremor totem,mana,wrath,wrath of air. On wowhead they said it is supposed to be like a debuff,but on feenix no debuff is displayed,nor a stats increase in character window. This is really something that will require a fix,especially since maybe other set bonuses dont work. Regards.
