MVC后动作没有正确绑定

我在ScenarioMeasures类型的Scenario模型中有3个属性。他们似乎是正确张贴，但ScenarioTargets数字被用于所有3个属性。我必须相信它们因为某种原因没有正确地绑定。为什么会这样呢?

模型

public class EditScenarioViewModel
{
    public Scenario scenario { get; set; }
    public IEnumerable<SelectListItem> locations { get; set; }
    public IEnumerable<SelectListItem> fiscalPeriods { get; set; }
    public IEnumerable<SelectListItem> effectivePeriods { get; set; }
}
public class Scenario
{
    //lots of other stuff, then...
    [Required]
    public ScenarioMeasures Adjustments { get; set; }
    public ScenarioMeasures BaselineData { get; set; }
    public ScenarioMeasures ScenarioTargets { get; set; }
    //more stuff...
}
public class ScenarioMeasures
{
    public decimal RGURate { get; set; }
    public decimal RevRate { get; set; }
    public int RevAmount { get; set; }
    public decimal VideoRate { get; set; }
    public decimal TSR { get; set; }
    public decimal Home { get; set; }
    public decimal CustomerRetentionRate { get; set; }
}

h2控制器

// POST: Scenario/Edit/5
[HttpPost]
public ActionResult Edit(int id, EditScenarioViewModel viewModel)
...
