Swagger example models not take DataContract.DataMember.Name override

For example, when i set attribute for action

[HttpPost]
[SwaggerResponse(HttpStatusCode.Created, typeof(Product))]
public async Task<IActionResult> CreateProduct([FromBody] MutableProduct model)
{
}

i get wrong Response Class (Status 200) description in Swagger UI interface. But when i call this method - response is correct.

I use NSwag 11.17.2.
