Guild Wars 2

I have a couple sets of armor. One for support that has a total of 97% increase in boon duration and also a set of Berserka armor for dps with no addition boon duration. My Attributes menu on the right shows everything changing when I change my gear except for the boon duration which shows 20% all the time. When I first made this set it use to increase up to about 60 to 65%. Is anyone else having this issue?

You might be looking at condition duration
