I did not have any gem with class key gem

I used a class gem key in U8 world for a class gem. I had 2 class gem key. I use one of them and got a class gem but bad stat so i tried a second time.

The problem : when I used the second class key gem, i didn't have any gem. I am so mad :/

I tried a relog but didn't work :c
