Using Serilog, I have implemented logging into multiple files but fileSizeLimitBytes not working

Question

I am already logging into an API file and would like to log into a different file for just one class. Therefore I used Filter.ByIncludingOnly to accomplish this, and it is working as expected.

However, it does not take into account the 'fileSizeLimitBytes' property. Once it reaches a size of 98 KB, it creates another file. is there any other way to achieve it?

 Log.Logger = new LoggerConfiguration()
         .ReadFrom.Configuration(configuration)
         .WriteTo.Logger(lc => lc
           .Filter.ByIncludingOnly(evt => evt.Properties.ContainsKey("SourceContext")
                && evt.Properties["SourceContext"].ToString().Contains("Web.Core.Helpers.ExcelReader"))
            .WriteTo.Map("Name", "import", (name, wt) => wt.File($"./Logs/log-{name}-.txt",
                rollingInterval: RollingInterval.Day,
                fileSizeLimitBytes: 200000, // File size limit for the 'import' key
                rollOnFileSizeLimit: true,
                retainedFileCountLimit: 60)))
         .WriteTo.Logger(lc => lc
            .WriteTo.Map("Name", "api", (name, wt) => wt.File($"./Logs/log-{name}-.txt",
                rollingInterval: RollingInterval.Day,
                fileSizeLimitBytes: 100000,
                rollOnFileSizeLimit: true,
                retainedFileCountLimit: 60)))
         .CreateLogger();
