Dynamic queue (5 premades) bug

I've found a bug when you go in dynamic queue with 5 people u can choose 1 role with multiple people leading to having the same role in champion select. As you see on the picture 2 people preferred jungle in queue and they both got assigned to jungle. It's not really bugging me since when u're all premade it shouldn't matter who goes what lane (in my opinion) but it's pretty annoying when u're not in skype or unable to communicate.
