WebApi. Custom route not working as expected

I'm trying to add custom route to the controller with [RoutePrefix("front")] that contains three methods:

[HttpGet]
[ResponseType(typeof(SparePartsFrontDTO))]
public async Task<IHttpActionResult> Get()
{
    ...
}

[HttpGet]
[ResponseType(typeof(IEnumerable<SparePartSearchDTO>))]
public async Task<IHttpActionResult> Get(string filter)
{
    ...
}

[HttpGet]
[Route("categories")]
[ResponseType(typeof(IEnumerable<DeviceCategoryDTO>))]
public async Task<IHttpActionResult> GetCategories()
{
    ...
}

But when I'm calling method by the route api/front/categories, instead of the custom route, default get method was called.

Here is WebApi config:

config.MapHttpAttributeRoutes();
config.MessageHandlers.Add(new PreflightRequestsHandler());
config.SuppressDefaultHostAuthentication();    
config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

The route prefix needs to have the desired template plus the other actions need Route attribute as well.

[RoutePrefix("api/front")]
public class MyController : ApiController {

    [HttpGet]
    [Route("")] // matches GET api/front
    [ResponseType(typeof(SparePartsFrontDTO))]
    public async Task<IHttpActionResult> Get() {
        //...
    }

    [HttpGet]
    [Route("filter/{filter}")] // matches GET api/front/filter/anything-here
    [ResponseType(typeof(IEnumerable<SparePartSearchDTO>))]
    public async Task<IHttpActionResult> Get(string filter) {
        //...
    }

    [HttpGet]
    [Route("categories")] //matches GET api/front/categories
    [ResponseType(typeof(IEnumerable<DeviceCategoryDTO>))]
    public async Task<IHttpActionResult> GetCategories() {
        //...
    }
}
