Guild Wars 2

I am curious if more then 1 TYPE of sigil can be used at same time. like for instance my axe has a minor sigil of bloodlust and my off-hand dagger has minor sigil of luck. I dont see a boon icon telling me i am getting both all i ever see is bloodlust. is this a current bug or can only 1 type be used at a time? also seems that if bloodlust is on 1 weapon set and luck is on another set even if i switch to the other set i dont get the rise in bloodlust per kill (obviously.. because im not using the weapon) but i dont get a boon icon for the luck increase.

Sigils with stacking effects will not combine with each other, you can only have one active at a time.
