Enum with 0 value not shown on Example

public class MyOption
{
[Option('t', "type", Required = true, HelpText = "My entity")]
public EntityType MyEntityType { get; set; }
public enum MyEntityType
{
X0, // Example for X0 is empty. If change this line to X0 =1, everything is ok
X1,
X2
}

[Usage(ApplicationAlias = "...")]
public static IEnumerable Examples
{
get
{
foreach (EntityType entityType in Enum.GetValues(typeof(EntityType)))
{
yield return new Example(entityType.ToString(), new MyOption { MyEntityType = entityType});
}
}
}
}

Start with the Examples property and its Enum.GetValues iteration in the reported reproduction, then trace how each yielded Example is rendered. Reproduce the case with X0 as the default enum value and compare it with X0 = 1. Done means the generated example for X0 is populated and displayed consistently with X1 and X2.
