C# Dapper Model not updating only one element

I seem to be having a problem with my model not updaing, but it seems there is only one aspect that.

I have the following setup

public class Stages
{
    public int ItemNumber {get; set;}   <-- seems to be updating correctly
    public string ItemName {get; set;}  <-- seems to be updating correctly
    public int ItemStage {get; set;}    <-- always results in 0
}

public interface IStageRepository
{
    List<Stages> GetAll();
}

public class StageRepository : IStageRepository
{
    private IDbConnection db = new SqlConnection(ConfigurationManager.ConnectionStrings["StagesConnection"].ConnectionString);

    public List<Stages> GetAll()
    {
        return this.db.Query<Stages>("SELECT * FROM Stages_vw").ToList();
    }
}

Under my HomeController I have the following

IStageRepository stagesRepo = new StageRepository();

public ActionResult Index()
{
    return (stagesRepo.GetAll());
}

Here is the schema of the view

TABLE_CATALOG   TABLE_SCHEMA    TABLE_NAME  COLUMN_NAME COLUMN_DEFAULT
WebServices     dbo             Stages_vw   ItemNumber  NULL
WebServices     dbo             Stages_vw   ItemName    NULL
WebServices     dbo             Stages_vw   Stage       NULL

If I do a "SELECT * FROM Stages_vw" in SSMS the results are correct

I have stumbled across these posts but I am feeling a little confused any help would be greatly appreciated

ANSWER per @chipples

This was due to a column name in the view not matching

dapper-simple-mapping

dapper-intermediate-mapping
