Mirage Deadeye and mirage archer works at the same time?

I started with the Ascendancy skill MIRAGE DEADEYE. And after a couple hours i'd added the MIRAGE ARCHER gem. But it seems mirage deadeye ( which is showed active in the top left of the screen ) stops working because i stop seeing the image of the skill's siluette anymore.

Is this a bug?, cause i only see Mirage Archer shotting :(
