HttpHeaderフィルターを追加すると、他のフィルターが機能しなくなります。理由はわかりません。

BaseApiController.cs

[ExceptionHandling, ApiValidation, HttpHeader("X-Robots-Tag", "noindex, nofollow")]
    public abstract class BaseApiController : System.Web.Http.ApiController
    {

HttpHeaderFilter.cs

namespace Tournaments.Models.Mvc.Filters
{
    public class HttpHeaderAttribute : System.Web.Http.Filters.FilterAttribute 
    {
        public string Name { get; set; }
        public string Value { get; set; }

        public HttpHeaderAttribute(string name, string value)
        {
            Name = name;
            Value = value;
        }

        public override bool AllowMultiple
        {
            get { return true; }
        }
    }

    public class HttpHeaderFilter : System.Web.Http.Filters.IActionFilter
    {
        private readonly string _name;
        private readonly string _value;

        public HttpHeaderFilter(string name, string value)
        {
            _name = name;
            _value = value;
        }

        public bool AllowMultiple
        {
            get { return true; }
        }

        public Task<HttpResponseMessage> ExecuteActionFilterAsync(HttpActionContext actionContext, CancellationToken cancellationToken, Func<Task<HttpResponseMessage>> continuation)
        {
            return continuation().ContinueWith<HttpResponseMessage>((tsk) =>
                {
                    HttpResponseMessage response = tsk.Result;

                    response.Headers.Add(_name, _value);

                    return response;

                }, TaskContinuationOptions.OnlyOnRanToCompletion);;
        }
    }
}

            return Bootstrap.Configure((kernel) =>

                    kernel.Bind<List<IPaymentMethod>>().ToConstant(kernel.GetAll<IPaymentMethod>().ToList());

                        .WhenControllerHas<ApiValidationAttribute>();

                    kernel.BindHttpFilter<HttpHeaderFilter>(System.Web.Http.Filters.FilterScope.Controller)
                       .WhenControllerHas<HttpHeaderAttribute>()

                       .WithConstructorArgumentFromControllerAttribute<HttpHeaderAttribute>("value", q => q.Value);

                    GlobalConfiguration.Configuration.Filters.Add(new ExceptionHandlingAttribute());

これを追加しました

TaskContinuationOptions.ExecuteSynchronously

それ以外の

TaskContinuationOptions.OnlyOnRanToCompletion

そして今はうまくいきます。
