Describe your environment. NetCore 6.0 OpenTelemetry 1.2.0-rc1 OpenTelemetry.Exporter.Zipkin 1.2.0-rc1 OpenTelemetry.Extensions.Hosting 1.0.0-rc8

The way I inject it：

 public static IServiceCollection AddZipKin(this IServiceCollection services, string serverName, string zipUrl)
        {
            var serviceVersion = "1.0.0";
            return services.AddOpenTelemetryTracing(tracing =>
            {
                tracing.AddConsoleExporter()
                    .SetResourceBuilder(ResourceBuilder.CreateDefault().AddService(serverName, serviceVersion))
                    //.AddHttpClientInstrumentation()
                    .AddAspNetCoreInstrumentation()
                    //.AddCapInstrumentation()
                    .AddZipkinExporter(options =>
                    {
                        options.Endpoint = new System.Uri(zipUrl);
                        options.HttpClientFactory = () =>
                        {
                            HttpClient client = new HttpClient();
                            client.DefaultRequestHeaders.Add("X-MyCustomHeader", "value");
                            return client;
                        };
                    });
            });
        }

Describe any aspect of your environment relevant to the question. Error request link display diagram：

What are you trying to achieve?

I think the correct display would be gateway--> PayAPI -->orderApi-->ProductApi,

I'm not sure if I'm missing something or is this a problem in the latest version

What did you expect to see?
