Gastly not letting me view it.

Again, another bug (seems to be plenty of bugs still in this game) I was playing against a gengar ex deck and they had a full art (or whatever) gastly on bench and active for parts of the game. They attatched a tool card to this gastly and I clicked on that gastly to check what the tool did but it wouldn't let me view it. When they evolved this same gastly into gengar ex via rare candy, I could view that gengar ex by clicking on it, but when I used devolution on that gengar ex, i could still not view the gastly.
