MVC 4 Scheduler : Days & Row Heights

From the code below is t possible to identify why the row lines do not match when the scheduler is rendered. The size of the event row is not matching the size of the row header.

Also, the scheduler is grouping correctly by month but the days within each month are not displayed below the month names.

Attached image to show how the scheduler is rendering.

I'm using the latest pro trial version.

@Html.DayPilotScheduler("dps", new DayPilotSchedulerConfig {
BackendUrl = Url.Content("~/Scheduler/Scheduler"),
EventMoveHandling = EventMoveHandlingType.CallBack,
EventResizeHandling = EventResizeHandlingType.CallBack,
TimeRangeSelectedHandling = TimeRangeSelectedHandlingType.CallBack,
CssOnly = true,
CssClassPrefix = "scheduler_blue",
StartDate = new DateTime(DateTime.Today.Year, DateTime.Today.Month, 1),
Days = 365,
CellDuration = 1440,
CellGroupBy = GroupBy.Month,
RowHeaderWidth = 120,
ViewType = DayPilot.Web.Mvc.Enums.Scheduler.ViewType.Resources,
ShowToolTip = false,
TreeEnabled = true,
RowHeaderWidthAutoFit = true
})
