skin selection-chroma bug

Every time i start a game with a champoion for whom i have some skins the skin i had previously selected appears and i simply select the next skin in line. That doesnt happen with the chroma skin i have. Every time i select pool party Leona and one the crhomas the next time i choose Leona the preselected skin is the classical skin. I know this is a tiny tiny tiny issue but i thought i should say something about it.
