Gr bug?

So lately I have been doing 5.2 but I've been stuck on 5.2.4 for some time, although the nodes aren't too hard. I have been using my duped 4/40 ghost rider and I fire off my l3 to reset my judgments so I can trigger regen again. however, my l3 judgment will not trigger a second time. in his abilities, it says it has a 100% chance to trigger, but it doesn't. this is unfortunate because I lose many fights and i am trying to use minimal units. Whats up with this?
