We are using Aspose.Slides for .NET 22.214.171.124 (netstandard2.0) library.
The old version of app using Aspose.Slides 126.96.36.199 and there same code works perfect.
The Secondary Axis show on the right side and Title also shown properly.
Using old version chart looks perfect

I was able to move secondary axis label to right using following hack
chart.Axes.SecondaryVerticalAxis.TickLabelPosition = AspCharts.TickLabelPositionType.High;
