Guild Wars 2

Hello,
I have 2 pieces of COF armor with "Superior Rune of the Ranger". When i move my cursor on armor or on pants to see the description it says: "Superior Rune of the Ranger (8/6)" but i have only 2 of them in 2 pieces. I had the same problem when i had just one rune, it said "Superior Rune of the ranger (7/6)".. what should i do? I attach a screenshot

It is a visual glitch. You really only have 2/6 and are only getting the stats for 2/6, but it is counting the 6/6 in your PvP gear in the visualization.
