InvalidCast Unhandled Exception

 I have a single series bar chart which when  hove over a bar causing it to highlight, it produces an invalidcast unhandled exception. It seems to be a problem with the template I am using to load the chart properties. If I just use the default properties (ie do not load the template) it produces a line chart. this highlights points with no problem. If I change it to a bar chart and hover over a bar, it highlights the bar successfully. If I use a template I get the described error.

I also found that if I clear the highlight it prevents the exception occurring.

The error message is

"Unable to cast object of type 'ChartFX.WinForms.Internal.SeriesPointIndex' to type 'ChartFX.WinForms.AxisX'."
