Elementalist Lux skin element glitch - You can choose the same element twice

Played a couple games as elementalist lux today. I was allowed to choose the same element I chose the first time - In this case air. Ended up seeing I could choose it again when I got enough for the second evolution. Clicked it, the circle above my portrait went black then suddenly changed me to fire. This is the second game I did where I wanted to try it again. Played a third one earlier, same thing happened with water but when I clicked on it, it just made me stay at water. Didn't let me choose another form and just retracted the same way it does when you choose your second form normally. Don't know if this just happens to me or not.
