Changing vtkScalarBarActor title justification has no effect

Hi all,
I’ve translated this example of vtkScalarBarActor into C#:

https://vtk.org/Wiki/VTK/Examples/Cxx/Visualization/ScalarBarActor

And am trying to change the left-right justification of the title text from “left” to “right” with the following line of code:
scalarBar.GetTitleTextProperty().SetJustificationToRight();

The command successfully changes the justification as confirmed by running:
scalarBar.GetTitleTextProperty().GetJustificationAsString();

However, there is no effect on the title’s appearance. Attached are two screenshots with the two different justifications and the title is in the exact same place.
