Xamarin.Forms SQLite WinPhone

I'm working on an app using Xamarin that will run on Android and Windows Phone 8. The app has a local database. It works fine on Android, but I'm facing a crash on WinPhone. When the app tries to update an item on database, it says "no such column: SendBill".

By debugging the app, I can see it calls connection.CreateTable<TTable>();, where TTable is a type of RouteMobile.

My RouteMobile:

public class RouteMobile: IModelBase
{
    public RouteMobile() { }

    [PrimaryKey]
    public int Id { get; set; }

    public int Code{ get; set; }

    public string Identifier { get; set; }

    public string DtExec { get; set; }

    public string Situation { get; set; }

    public int SendBill{ get; set; }

    public int QtdBillsToPrint { get; set; }

    public int QtdNotificationsToPrint { get; set; }

    public int QtdDebitNotificationsToPrint { get; set; }

    #region Sincronization

    public Int32 IdServer { get; set; }

    public DateTime SyncVersion { get; set; }

    public Boolean UpdateFlag { get; set; }

    #endregion

    [OneToMany(CascadeOperations = CascadeOperation.CascadeRead)]
    public List<RoutePointMobile> RoutePointList { get; set; }
}

My IModelBase:

public interface IModelBase
{
    int Id { get; set; }
}

Then, the app app calls connection.Update(item);, where item is a instance of RouteMobile, it crashes:

{SQLite.Net.SQLiteException: no such column: SendBill
   at SQLite.Net.SQLiteConnection.Update(Object obj, Type objType)
   at SQLite.Net.SQLiteConnection.Update(Object obj)
   at IM.Data.BaseMobileDAO`1.Save[T](T item)
   at IM.Business.RouteMobileBO.Save(RouteMobile item)
   at IM.Business.RouteMobileBO.AjustRoutes(IList`1 lstRout)
   at IM.ViewModels.RoutListViewModel.get_ListRouts()}

Running on Android, it runs fine. On WinPhone it crashes.

Any idea?

Thanks!
