Configuration on json Appsettings not filtering the levels.

[alexmbra]

Description When I use filters from code, it works. But when I try to use them on the configuration on json Appsettings file, it does not filter anything. It writes everything on all log files.

Reproduction This works:

var logger = new LoggerConfiguration()
               .MinimumLevel.Debug()
               .MinimumLevel.Override("Microsoft.AspNetCore", LogEventLevel.Warning)
               .Enrich.FromLogContext()
               .WriteTo.Logger(
                   x => x.Filter.ByIncludingOnly(e => e.Level == LogEventLevel.Error)
                       .WriteTo.File("../logs/error_.log", formatProvider: CultureInfo.InvariantCulture, rollingInterval: RollingInterval.Day, retainedFileCountLimit: 30)
               )
               .WriteTo.Logger(
                   x => x.Filter.ByIncludingOnly(e => e.Level == LogEventLevel.Warning)
                       .WriteTo.File("../logs/warning_.log", formatProvider: CultureInfo.InvariantCulture, rollingInterval: RollingInterval.Day, retainedFileCountLimit: 30)
               )
               .WriteTo.File("../logs/all_.log", formatProvider: CultureInfo.InvariantCulture, rollingInterval: RollingInterval.Day, retainedFileCountLimit: 30)
               .WriteTo.Console(formatProvider: CultureInfo.InvariantCulture)
               .CreateLogger();

           builder.Logging.AddSerilog(logger);

But this does not:

var configuration = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json")
            .Build();

            var logger = new LoggerConfiguration()
                .ReadFrom.Configuration(configuration)
                .CreateLogger();

            builder.Logging.AddSerilog(logger);


      },
      {
        "Name": "Logger",
        "Args": {
          "configureLogger": {
            "Filters": [
              {
                "Name": "ByIncludingOnly",
                "Args": {
                  "expression": "(@Level = 'Warning')"
                }
              }
            ],
            "WriteTo": [
              {
                "Name": "File",
                "Args": {
                  "path": "../logs/warning_.log",
                  "rollingInterval": "Day",
                  "retainedFileCountLimit": 30,
                  "outputTemplate": "{Timestamp:o} [{Level:u3}] ({SourceContext}) {Message}{NewLine}{Exception}"
                }
              }
            ]
          }
        }
      },
      {
        "Name": "File",
        "Args": {
          "path": "../logs/all_.log",
          "rollingInterval": "Day",
          "retainedFileCountLimit": 30,
          "outputTemplate": "{Timestamp:o} [{Level:u3}] ({SourceContext}) {Message}{NewLine}{Exception}"
        }
      }
    ],
    "Enrich": [
      "FromLogContext"
    ],
    "Properties": {
      "Application": "MultipleLogFilesSample"
    }
  }

Expected behavior Both codes are suppost to filter the log entries by level and write them into the respective files.
