Gear shift

Hello Motor Talker I noticed what happened to my Chrysler Sebring Cabrio BJ 2002 and that makes me stutzig so that I would like to know if this is normal I will upload 3 photos probably can even tell me which part is missing and which spare part I need. It’s about the part with the white head or ring which moves the gear mechanism and somehow this is just loose on it and I can’t imagine that it belongs like that. Thanks for your H Help your Matzy
