Saw this earlier today. I wish I had some better repro steps, but the closest I have for it is:

1. Pick a pre-made group (ideally 4 people)
2. Have them set their secondary role as mid/etc
3. Invite a 5th player
4. Start searching for a game.
5. Observe that, occasionally, it will display more than 1 person's role as the same.
