Riot gave me the mark of shame (dynamic Queue badge.) after duo queuing for one game.

Title. I'm mostly a solo player when it comes to playing ranked in league of legends, but I might meet some people or know some people on my friends list who are similar in ranking with me and duo with them. I had the solo badge for quite some time now and duod ONE GAME with a leona main. After that game riot or the system gave me the dynamic queue badge when I only duod once. I thought they took the information from your last 25 wins? Did they change anything or is this a bug?
