MVC3 view rendering twice when I have Glimpse and use a MVC control toolkit DateTimeFor element - asp.net-mvc-3

Question

I have an MVC application with glimpse installed, I am also using the MVCControlToolkit for dymanic validation.
The issue I have is when I have a view that uses DateTimeFor to display the date time calendar with validation, but only in a very limited set of circumstances (if I only have datetimefor elements this doesn't happen), the body gets rendered on the page twice.
It looks like the rendering is getting restarted by something, but I haven't been able to work it out.
Any help would be appreciated
My view code is
#using LeaveTracker.Models
#using LeaveTracker.Models.Leave
#using MVCControlsToolkit.Controls
#using MVCControlsToolkit.Controls.Validation
#model LeaveTracker.Models.Leave.LeaveAllocation
#{
ViewBag.Title = "Edit";
Layout = "~/Views/Shared/_LayoutMaintenance.cshtml";
}
#Html.AntiForgeryToken()
<div class="page-header">
<h1>
Edit Leave Allocation
#if (Model.ID > 0) { <small> #Model.TypeOfLeave.Name till #Model.AppliesUntil.ToString("dd/MM/yyyy")</small> }
</h1>
</div>
