Virtual Event Session Start/End not set by mixpanel

Virtual Event Session Start/End not set by mixpanel Hi everyone, I am facing issues regarding mixpanel automatic session management (see the picture). I require the help of this excellent community for solving the problem. I am sending event from my Spring Boot application using mixpanel Java SDK. I am using timeout based session in my project settings. Each mixpanel event is having the following properties

{
  "event": "LOGGED_IN",
  "properties": {
    "time": 1740237123.615,
    "distinct_id": "YWRtaW4=",
    "entity": "start",
    "environment": "dev",
    "mp_lib": "jdk",
    "session_id": "54155470-7ac4-48c9-ad18-0fa561d12fe5",
    "user": "admin"
  }
}

I have also tried with the property based session but that also does not work for me. What am I missing? Should I send some additional properties from my application.
