为什么不能按配置文件更改日志类别的日志级别?

{
  "Logging": {
    "LogLevel": {
      "Console": "Critical",
      "Default": "Warning",
      "System": "Warning",
      "Microsoft": "Trace"
    }
  }
}

我用来加载配置文件的代码:

        hostBuilder.ConfigureLogging ( ( context, builder ) =>
        {
            builder.AddConfiguration ( context.Configuration.GetSection ( "Logging" ) );
            builder.AddConsole ( );
        } );

Information 类别的日志级别: System , Microsoft Debug 对于 Default . 我哪里出错了?
